ScooterBob & GHG's C-5 Cafe Racer project
« on: March 30, 2013, 09:49:26 AM »
   Here you go, some pictures of the finished Bike.  In a nut shell, we set out .... A WAYS back, to take a great handling, great looking C-5 with a great motor. And turn it into a Great looking great Handling C-5 Cafe Racer.... and add some GO FAST to that great motor. And depending on your taste..... I think we did alright.

    From concept, design, fabrication, etc....etc. All done in house....That would be my house and Scooterbobs...... By hand and by us. We put a lot of thought and detail in it, and I have a bunch of build pictures of it. So if you are interested... ask. I may have a shot of it.   Thanks, and I hope you like it !  I sure do......

Very nice work! Such a good looking bike that is. Very tempting. Awesome work by ScooterBob and yourself! I hope you have lots of fun with it. Ride safe!  ;D

Also, just for future reference, you can attach up to 4 pictures in one post. When you "Browse" for a picture, there is a "(more attachments)" option underneath the textbox.  :D

I am guessing the 535 in the license plate is the scooterbob trademark "no replacement for displacement." Right ?

   Once again Guys, thank you..... Feeling a bit humbled.

   And I'll tell you what bareneked, I have been admiring your bike for a while now! Love it !

    DanB...... Thanks, a Gasman has to have some gas fittings on a bike ! ;)

     And about the details in the graphics and on the bike and all......  GOOD EYE's!  The graphics were pulled together by my very talented. graphic designer niece  Erin. She pulled together the idea's that scooterbob and I through at her quite nicely. There are filled with subtle and not so subtle images, hints and clues if you will.

  For instance, Ducati Scotty mentioned the " air scoop" graphics. You'll see the Isle of man symbol.....and if you can zoom in enough, you may be able to make out scooterbobs and my initials in the gun stocks.  Hammer for me and micrometer for scooterbob..... only fitting I think. The silver paint on the frame is a nod to Mike Hailwood..... don't think he ever raced on an Enfield ?  But he is just cool !!  Also in it's way, in the body work, there is a nod to both Hailwood and Tommy Robb.  There is a lot more here and there........

   Thanks !  Something different I just wanted to try on a Cafe seat. These bikes spend all there time on the road and NOT the track.  Pot holes and such..... those seats are hard man ! They are Harley seat spings and  I limited the seat travel to about an inch..... just for a little cush.

It looks like that seat pan is designed for hinges. What bike was it originally designed for? It looks great on the C5.

     WOW !  Your good !  Just like the stock C-5, there is a lot of ..... "International" to the parts
 that were added.

Looks killer.  Great paint job - I really like the knee cut outs a lot.  The graphics are great and really well done - Nice color choices.  Real classy, front to back.  That tail light is great... gives it character and makes it look like a rocket thrust.  Speaking of... how is the performance?

You guys should be, as I'm sure you are, pretty damn proud of this one.  Probably one of the nicest Enfield's on the planet.

   Well .... I don't know about the Planet Boggy ! There are a lot of cool Bikes out there man.  But I'll give you at least the Nicest in my town. Thanks man, and yes, very proud.

   The Tank indents were hammered in and smoothed out. And that tail light was a pretty cool and wild Idea by ScooterBob.  It's a '59 Caddy  "bullet"  tail light.  Mounted into a housing, made out of a 3" truck exhaust pipe . With a hole cut out of the back of the seat cowl. Housing welded in, and the hole beaded in  3/16" round stock and smoothed.

  The performance is pretty darn good. And the motor work has been done in stages. It's NOT a 535 yet !  And I'm not painting that fender twice !   He..he...he   Starting last season after the bike was fully put back together. Scooterbob did a "little" Head work and we ran and tuned that for the summer and fall with good results.   Over this winter, he ground the Cams. And we have been busy working on those. I made adjustable push rods and converted the Hydraulic liters to solids. General dialing in and testing and such for the past month or so. And finishing it up with some Dyno time and tune yesterday with the PC-V.   The results were  29 and change HP and 31 and change Ft. lbs at the rear wheel. Not too bad !  Peaks around 4800 rpm's Just before it goes into a soft cut on the limiter at around 5200 rpm's.  So, at this time there is no need to use the rev extend feature on the PC-V .  it's would just free wheel the bike , with no gains.  And the Motor has some pretty dam! good cooling features!  We were probably in that booth for two hours and i don't think the motor got over 195 degree's.  BIG thanks to Shawn the tuner over at JDS Cycle..... the guy is amazing to watch!   Man..... everybody needs one of those machines in there garage ! Amazing the things it will tell ya....

Anybody can up the displacement and go faster .... it takes a couple of REAL (stubborn Irish) men to "run what ya brung" and make it go faster. The displacement trick is probably next - with a different piston crown design ..... Heck - that little hotrod heep still has the stock piston in it!! Hahaha!

Amazing work! I can't wait to get to my laptop so that I can see the photos full size. The solid lifter conversion and head work is intriguing to say the least. I'm impressed that you guys increased the hp 50% under the stock redline and efi system! Any pictures of the solid lifters and adjustable pushrods?

   Thanks !   I do have pix of the lifter conversion.  But unfortunately I do not for the adjustable rods.  But , they are a simple Harley type arrangement , with threaded rod and lock nuts. The lifters from the exterior, look the same as the Harley like lifers used on the bike. The inner works were simply removed, And an alloy slug machined and fitted in place. The stock Lifter cup is retained..... and stronger retaining "C" clip is used in place of the stock retaining spring.

   We really wanted to retain the stock hydraulics, They are good little units. BUT, for our performance mods.... They just did not pump consistently enough, and lifter pump became an issue.  Not sure if these stock lifters are from a Harley ? But they are not from a late model sportster.... I grabbed the anti- pump versions of those.   And they are not even close to whats in the UCE.  Different size and arrangement..... But similar in appearance. So the solids became our alternative.

  Stock springs were retained, also the stock valves were used.... though modified. Stock rockers and blocks. All put under some heavy flogging last year, with some pretty high compression. Not a problem.   When the head was off most recently, the valves and seats were fine. The surfaces didn't need to be touched, and held fluid for well over 24 hrs.

  LOL !  Yeah, pretty cool how it drowns out the Stones in the background completely. That piece was with the head only and in a decent state of tune.  MUCH louder now. A more Machine gun like POP !

   In the baseline dyno one.  That was our first pull . Head only . With TPS adjustments. No PC-V. AFR's were pretty much dead on the line.  That was a fourth gear pull , with stock gearing.  You can hear and see it hitting the limiter pretty quick.  Gearing changes had to be made. And as predicted by ScooterBob, There is significant loses through the props , between fouth and Fifth.

AFR's were pretty much dead on the line.  That was a fourth gear pull , with stock gearing.  You can hear and see it hitting the limiter pretty quick.  Gearing changes had to be made. And as predicted by ScooterBob, There is significant loses through the props , between fouth and Fifth.

I have no idea what you just said.  But... it sure sounds exciting!  We may be riding the same brand of motorcycle, and even speaking the same language, but...  ;D

   Yeah........ You know Matt... Looking at that now !?   Whut the hail kind of Jersey gibberish is that !?   He..he..he.

   Let me try that one again......
   On our first test on a Dynometor,  With ScooterBobs  modified cylinder head. A freeer flowing Intake and exhaust, And only adjusting our air fuel Ratios in the combustion chamber by settings on the throttle position sensor.... using voltage readings. "Using my butt Dyno" and inspecting the spark plugs, and trial and error and such. We were able to set the air fuel ratio to the nice and rich side of Stoichiometric..... which would be around 13.2 to 1.  I know...I know..  Images of a geeky guy named Stoich comes to mind.  Here......

https://www.youtube.com/watch?v=kZaCKyoMQVM

  Also we found that the bike makes more power in fifth gear then fourth.  And I needed a bigger toof sprocket to keep me from hitting the RPM limiter so quick. The RPM Limiter is built into the computer on the bike...... which is a good thing...... to prevent someone from blowing up their motor. There is a bit of wiggle room in there...... but it's best to keep it where it is, and change that ONLY if you need to.  The rev limiter works by cutting off the sparks and the fuel. 

 A POWER commander V, type devise. Is a thing that will Trick the bikes computer so one can make changes to the stock settings in that stock computer. And adjust the sparks and fuel.

You guys have built a great looking cafe racer out of C5!!...Wonderful job!!...Cant take my eyes out of the pictures!

What is the gauge for and is this still EFI? what are the engine mods that has been done?

great to know the stock EFI can handle increased HP.  What pressure are you running the injection ?  also, is your regulator vacuum modified ?  stock injector -or- higher flow ?

     Thank You !

   Yes it is still the stock (keihin) EFI system. The gauge is so I can see the fuel pressure. The gauge is mounted upside down, so as I'm riding the bike. I can simply look down between my arm and chest and see it.

  Engine mods as of today:

  ScooterBob JJ Head
  ScooterBob JJ cams
  Solid liters
  Adjustable push rods
  Modified stock head pipe... restriction cut off " Lava Rock Fiber" heat wrapped.
  Emgo/ Hitchcocks  Reverse Cone Megaphone
  Velocity stacked turn out, intake runner.  Adaptable to a pod filter
  Power commander V  For the 2009-2013 UCE Bikes, Piggy backed.

    Yes it is Gremlin !  Stock fuel pressure.... 42 PSI.  Stock injector, with plenty left.  Fuel is regulated back to the tank using a Bosch/ VW Regulator. It has a range of adjustment on the Vacuum "Pub".

What a beautiful straight line- gotta love long stroke engines!  Very impressive work. It makes me wonder what scooterbob's cams alone would do for hp gains, unless the stock lifters can't handle the extra lift?

   Yeah, these ARE are great motors ! And ScooterBob did some very nice work with the parts. Burned up a little cray matter on this one !  he..he..he.  And hopefully we both have a few more wrinkles in the brain. That's an interesting thought on the Cams with a stock head........... Certainly the valve train geometry would be looked at. Clearance issues and such.....
 I am sure SOME hydraulic lifters would work. I personally like solids for their consistency.  BUT, Hydraulics have been used for years successfully in Cars and bikes  for performance applications.

   You would also have to address the changes in air flow through the intake, it's effect on the map sensor..... If any.  Voltage readings the it's sending back to the ECU and etc.  Basically a new map would likely be needed. etc.....etc.....etc.  You can't just stick parts on..... intake, exhaust, Cams. And expect the stock ECU to adjust to these changes.... The ECU does have some learning in it, I believe. BUT to do it without thinking you will not have to make changes In the AFR's ?........... You may get away with it , with a filter or muffler?  But modern bikes come pretty lean from the factory.   So basically....... yeah, some things to look at.

IF my calculations are correct, it should show us about 112mph on the dyno .... which ought to be about the ton in real life. Gearing is still an issue - we just haven't haven't had the road time with all the new tuning to suss it out - but the power's there. REAL, honest to goodness Scheidler Steam Traction Locomotive power. Stay tuned .... I can't have the Crash Test Dummy riding in the cold!! Hahahaha!

    Well thank you Tom.  I'm sure you can appreciate the amount of work that goes into these projects.   And sleepy Suburban NJ towns !? ......Are there any left?  ;)   Oh..... that's right !  Way out to the south and west of here ! LOL ! As a matter of fact I think that would be great fun, riding with Chumma. Setting of Car alarms and cracking windshields..... from the sound.....
 I can imagine the confusion, on the harley types faces.... as the bikes come down the street.  "A double lung Sporty drag bike..perhaps"    He...he..he..  NO !

   And give my regards to Chumma, It would be nice to bump into him again. I am on the west side of Elizabeth. And if he is ever in the neighborhood, he is certainly welcome to stop by. But warn him, if he should bring the Fireball. To lay off the throttle some, as he comes down the street...... I think maybe, the town has a cop car stationed down the corner...... You know. 8)

Thanks for the kudo. I was doin' what I do best on the bike - TUNE! I figgered that the budget approach was the best - hence all the stock hardware - and the sweat equity. I've always done it that way - I've never had a pile of resources - but I've always to squeeze the stock stuff and make it a little better. Just remember - parts is parts ..... until you add the LOVE! Hahaha!

BTW - I gotta add this. Use someone with a good dyno that knows how to use it. Our original results were skewed to the "fantastic" level by a goon running a dyno at the local Harley-Davis joint.  :'( So every Sportster that's ever been on THAT dyno is probably 200 horsepower.  ::) Harley horses are obviously smaller, so you get more of them into an engine, I think. Anyhoo - the current rear wheel power on the dyno is correct, I believe. Not as big a number as before - but Foe Rill .... and quite impressive to ME with just a little tuning!

I also gotta thank the Gashouse Gorilla for being the Crash Test Dummy for all my parts! You'ze Da MAN!! (in best Jersey accent!)  ;)

  No

    Well..... I thought a two inch ball valve would be a bit overkill, for the pressurized EFI system.  :o    The 3/8 Brass valve and fittings worked out nicely, and they are functional for how we hooked up the fuel system. It's nice to have a Valve for maintenance reasons, as well as a sediment trap with a plug , to drain the Tank and system down.  Also because of the external pressurized fuel lines...It's not a bad idea to have a big handled valve ;)  I Figured I might take some flack for that.....But I like the brass, and I used it on the last Cafe I did.  Looked cool I thought.... Matter of taste I guess. ;)

  Thanks  ! ;)
  It is gremlin.... should the valve be accidentlley shut off While the bike is running..... Although not a good thing... The system will slowly lose pressure.... The bike will stall, and the pump will cut off. Re Priming the pump, is not a problem, a couple of hits on the kill switch and it primes it right up.

  Sooo... The Stock ECU Controls the inline pump that we used. Just like it would the stock pump ...... Nuttin' going on in the combustion chamber.....no pump. And most of the left over pressurized fuel in the line, get burned off quickly.
 We didn't use a separate "Switched"..... like a toggle..... pump circuit to run the pump.

   Whelp, weather is cold so it's time to get back into it and see what else we can do.  From the frozen Tundra of the mid way, a nicely worked cylinder and a beautiful forged .020 over AVL piston from ScooterBob.  The Cylinder was over bored a bit... for a nice fit. And also some pretty nice fin work, with the alternating paint and polish.

GHG - About that, I wanted to also tell you that when I put my box fan on low behind my catalytic heater it acts like a forced air heater and heats up my garage to 75-80*F in less than 15 minutes.  Then I usually shut it down for about 20 minutes or so and repeat the process.  A 20# cylinder will last me a couple of weeks of regular use and the only time I get cold is when I run out of gas.  ;)

Well done!

   Thanks !


So shiny!  The precious!

    The shiny should .... besides cleaning up the ugly tool marks........ Help to make the arms even a little lighter,  by making it easy for them to shed or "flick" oil off. Which would other wise accumulate on the rough and pock marked surface.  In theory anyways....  Every little bit helps.  A little hear , a little there and all.... But I really just could not stand the way they looked unfinished.


 
I see stuff like this and I get a strong urge to start taking my bike apart - just for fun!  :o

What's wrong with me?


   Nothings wrong with you Matt !......  Go get some and learn along the way. This shit is Fun !

 It only takes a couple/few hours , with some basic tools to do it. Dremal...grinding wheel or belt sander... fine sandpaper...polishing wheel, and etc.  Get creative and use what you got. Just leave the ball, shaft, and wipe surface alone.  And you don't need to spend a mint ..... you already HAVE rockers . ...

 It should help to let the bike rev up quicker, let the valve spring spend more time controlling the valve, instead of that massive weight on top of it, less wear and tear on the valve train and etc... lifters, rods and etc.  Little things add up....


@gashousegorilla...for better heat in the garage...nay I suggest "Jameson's".  ;D

   Oh yes Brother..... I do believe in some internal heating as well  ;) 8)

   That is an excellent Idea Scottie..... I love it !  THATS being creative !  And you are SMART to shut that sucker down every once in a while.  Most Cats don't.... that Co can kill ya if they let it build up.  I have been responding and investigating those calls for many years..... It can get ugly.

Nice work on the rockers!  I didn't know what they looked like originally so thanks for the pic.  Back to heaters quick:  I also pop the door open every couple hours to get some fresh air  in the shop too.  I learned my lesson in my early 20's doing a S10 small block swap.  It was a cold ass Wisconsin winter and had the torpedo kerosene heater running for about 4-5 hours and about 1am almost passed out.  So yeah.  Lol

Well ...... Sometimes the ol' BSA got tore up as well. This is how one learns just HOW light a part can be ..... A really good current example are the connecting rods on the new 111-inch Polaris/Indian engine. They are not the pig-iron of the past, but rather very carefully engineered, powder-forged beryllium steel parts that are as strong as they need to be for the demands of the engine ..... and they are LIGHT, man! They put me in the mind of the Sportsman rods that I used to build the stock car engine with. They were about half the weight of a pig-iron Chev-uh-LAY rod - and just as strong. They'd handle about 14:1 compression and 8800rpm's ...... with a nodular iron crank that was 35 lbs. lighter than a forged one. Rev quick? You bet! You'd ping the rev limiter faster than you could pin and release the throttle at the carb. The old BSA was close ....... EVERYTHING in that engine went on a serious diet!  ;) Hahaha! Grindin's cheap .... PARTS are expensive ......

Ignorance (mine) in the house here: Are those typical gaps?  Seems like a big opening for the gasses and forces of combustion to leak out - but obviously it must work...

   Where's my Ring compressor !!....... All fired up now Cuz


 Piston installed, rings in place.  notice the Ring gaps.  Piston and cylinder get lubbered up.....

I must slightly correct this ...... ring gaps should NEVER be on the thrust side of the piston. When the piston "rocks" in the bore under combustion pressure, it's possible to dig a ring corner into the cylinder wall. I like to place the compression rings 180 degrees apart, halfway between the pin and the thrust side of the slug. Nit picky? Yeah .... but I can't help it! Comes with the territory, I s'pose  ;)

  And slide it on there.  I like to use a 4" hose clamp to compress the rings.... Install the studs and torque 'em down.

What deck height did you end up with ...... I'm curious. I'm GUESSING about .015" down in the hole? A stocker is around .040". We don't any of those compressions to get out, you know!  ;D

Ignorance (mine) in the house here: Are those typical gaps?  Seems like a big opening for the gasses and forces of combustion to leak out - but obviously it must work...

Matt - the gaps are measured in the bore. The way they appear on the slug when it's out of the hole has nothing to do with the finished install .... they'll squish right down in there! Hahaha!

Ah.  Thanks!

ScooterBob, you're answering posts faster than I can read them!

ring gaps should NEVER be on the thrust side of the piston.

As in, the ring gaps should line up with the pin, rather than be 90° off?

Ah - gotcha.  I imagine you'd get the most side thrust during the power stroke, but also perhaps some on the opposite side of the piston during compression?  Even though the piston is traveling in different directions, there's still a "downward"(i.e. away from the head) force during each phase...

    Yes..... You could also just remove the tappet ( lifter)  inspection cover and grab them that way. But , who wants to reseal that cover if you don't have to.  There is NO gasket on it.... just goop.  I should make one, now that I think of it ?

   D' OH  !! ......... LOL !  Your right Scott.  ;)     I should been more clear, and stop thinking out loud as I type !   Of course... no need to with Hydraulics.   But I'm using adjustable rods, and it would be nice to adjust, through the cover back on after I adjust , with a Gasket.  I'm always thinking about this stuff... and... Sometimes things just leak out of my brain uncontrollably  :-\ ::)   


    And ... while I'm thinking about it.    Does anybody out there, have a line on where I could find some threaded pushrod top cups?   These are ones I used to make up some rod length checkers from Jegs.  And they work really nice..... nice easy adjustment. BUT ... they are soft  metal, and won't hold up to my thrashing. they are for checkers only...... The rod builders out they don't seem to make them is this particular configuration.

   Don't think we have to worry about that Cuz..... NICE work I must say !  ;)  More like ....005  EXcellent !

  Sooo... all socked down with stock base gasket and three sectioned stock head gasket.. we come up with....

   65- 70 thou valve to piston clearance at TDC... And puts us in the quench band at 60 thou.. With a little wiggle room on the three sectioned gasket. Think I'll give it a go like this first....

  Whelp.... after a LONG cold 7 day work week last week.. I was able to get back on it today.  And i was able to button up the top end.  And it IS  a nice bump in compression.   And I have NO doubt that the that the AVL piston crown will look as clean as the stocker did, with ScooterBobs combustion chamber design  ;)

  A few more pics.... not comprehensive, but just as I go along..


   Copper sprayed head gasket...reused and in perfect shape.

   Sliding the head nuts down to the studs, using a long thin screw driver shaft , makes things easier.   There are TWO nuts under the rockers.... so if you don't see 'em? You need to take the rockers blocks off !  And.... torquing them down crosswise.  I like to sneak up on the torgue spec ...give the head a few TAPS with the mallet, then finish off torquing it down.   Let the head sit for a while.... then check the torque again.

Sweetness!  It definitely sounds more snappy and than I remember from the video you posted in the spring.  Listening to the exhaust note, it has that distinct "pop" generally associated with a higher compression motor that you don't hear on a standard UCE motor.  I'd say mission accomplished.  ;)  What was your previous top speed before you tore the top end down again?  Did you do a cylinder compression test to get a relative idea of the compression bump achieved?

Sweetness!  It definitely sounds more snappy and than I remember from the video you posted in the spring.  Listening to the exhaust note, it has that distinct "pop" generally associated with a higher compression motor that you don't hear on a standard UCE motor.  I'd say mission accomplished.  ;)  What was your previous top speed before you tore the top end down again?  Did you do a cylinder compression test to get a relative idea of the compression bump achieved?

Scottie

    Yeah, it definitely SOUNDS sweeter.... But also maybe a little restricted. looking at THAT today.  But I want to at least get it out for a run today if the rain stops. Compression  IS up as you can hear......   I did show 94 , on the GPS on my phone during the summer.   For top speed stuff, as opposed to good mid range ? Yeah... I think we'll have to take a look at the gearing  and probably that header.

  Yeah, and crackley and poppy...... Might be time to make a bigger header.  Took a little closer look at the stock header today.  It is actually quite well made... if not I little small for my needs now....  Something we did not see earlier. Down near the silencer connection ,the double wall pipe also houses an anti-reversion hole and chamber...pretty trick.

   The top of the header... port side... with flange cut off showing the small inner tube, and expansion chamber. The smaller tube is also restriction for the O2 sensor...so it can get a good read on things. As predicted by ScooterBob
.  And trying out different flange arrangements for the new pipe....

  I bailed out on buying the pipe bender and stopped into a muffler shop this morning, where Herb the owner attacked it like a mad scientist ! He was very into it, and did a outstanding job.  ;)   

   The new header bent up with new flange..... And on the bike, ready to be tuned and cut to length....

SB:

From this basic tutorial link, it is clear that since you read and understand this kind of material of quadratic equations polynomials ... written by PHDs, you must have alphabets like FRCMDPHDBEMES... behind your name, you just won't admit ;).  Thanks for the link.

Quotes from the Tilden Technologies -

"Most automotive enthusiasts are easily exploited because they don't understand camshafts and cam design.  We have developed this website to share what we have learned.

Larry got his start with numerical methods back in the 1970's using the Orthogonal Collocation method.  When this method was picked up for simulating valve spring dynamics, he realized that some aspects of the method were never explained very well.  For this reason, he developed a hands-on tutorial on the method which includes downloads of code in Fortran 90, C++ and Excel.

Vita Larry Young

Larry received a B.S.Ch.E from Texas Tech in 1970.  An M.S.Ch.E in 1972 and Ph.D. in Chemical Engineering in 1974 both from U. of Washington.  He spent 1975 thru 1983 in the Research Department at Amoco Production Co. working in petroleum reservoir simulation and enhanced oil recovery.  In 1984 he founded Reservoir Simulation Research Corp. with a principal business of development and licensing of reservoir simulation software.  After selling the company in 1996 and a brief period with the successor company, he retired from full time work.

So does the jerk jerk the jerk cams to the left and right in a circular motion to get just the right amount of jerk needed to jerk the valves with the jerk cams?

    That's the hardest part of it Dave !..... But then again, we have a pretty long winter around here. ;)



 
Hey GHG just wondering ... Why did you change your fuel pump ? Was it not moving enough?


  No special reason Dave. I just chose to use a different tank for the bike.  Although it WOULD HAVE been much easier to use the stock tank.. . I just liked the tank I chose , with seat /cowl and fender combination.  Just thought the proportions looked right for the bike... to me at least.  But , keeping the stock RE front end.  I was just thinking...... it had to look like a Cafe Racer, but it had to look like it was a RE Cafe Racer ..... You know ?  And retain the distinctive front end.. Otherwise it would look like every other Cafe' out there, except with a different motor.  :-\       AND...... I had made the tank and tins for another project. But, honestly I lost complete interest in it shortly after getting the C5.  Ruined me for other bikes ...

  Ok, a little up date on the most recent mods to the bike over the winter..... Finally got some time to get it on a Dyno, and get a tune on her and see what she can do. Besides the AVL piston, lightened rockers and etc. We put in some new valve springs, beehive's... retainers and keepers. To further lighten the valve train AND to keep it under control for the added 1000 RPM's we can now rev it to, with the rev extend feature on the PC-V.   The result's are 33.25 HP and 34.75 ft lbs of torque at the wheel.  Or about another 10 % increase over the previous set up.  I'm guessing ?....  We are in the neighborhood of 40 HP give or take, at the crank .
   
  Also, we are trying a intake mod that mounts in the intake manifold which is showing  promise and gains . It's called the  "FIN" .  Developed and tested by local tuner's  Pete Burger and Shawn Eisenmenger on other applications . It basically helps with the flow in the manifold by reducing the air drag on the walls of the manifold. We are playing with that now and see what we can do.

 Thanks Scottie  ;) ......   BTW, how much do you weigh ? ???   ;D

  It should and yeah Tom, the power is getting up there, little bit at a time.  We'll see how it does this summer ?   Maybe I'll get it out to an air strip in the Midwest . Might need a little lighter rider?...... See above  ;D


Wow!  You're getting a snot load of power out of that thing.  Nice move with the beehives to combat the valve float.  I'm looking forward to more info on the intake mod.

Scott

  Yeah Scott the springs help....A LOT ! They are comp cam springs , retainers, keepers. The seat cups are from Ferrara...And if I remember ? The lash caps are from Manley. It all works nice together.  I did a pull on the dyno about a month or so ago, extending the limiter at that time. And the stock springs are useless above  5500 max and done AND blowing out the intake at 5800. My numbers were roughly the same back then, maybe a little lower?  BUT much harder to get there. So we stopped tuning and testing, and ScooterBob and I put our heads together and cam up with some springs. They seem to be working nicely up to 6000 , and all you can see, that's all I need right now. Enough spring , but not too much. Also if need be in the future, seat pressure and over the nose can be adjusted.

   As far as the Intake mod it's an interesting devise... He sets it up on a flow bench I believe. And positions it based on you motor and mods... if any mods. And kick's in above 2500 rpm's so I understand. Positioning is key I believe.  So we'll see ?  it's pretty cool, and I'll test and play with anything.  I my case on this first go around ... it bumped up the horses a bit in the mid- to upper range.

CONGRATULATIONS GHG !!!

    LOL !   Thanks for the encouragement Singh  ;)   

 I was actually thinking of you in the Dyno booth, and wished I had a camera !..... Dangit ! It's very interesting to watch the cooling features of these motors, really outstanding.  At a cold start you can see how the injector is cycling a bunch of fuel... but the AFR reading at the header through the sniffer is very lean.... like 18 to 1.  BUT, as soon as you pull that by-starter  it goes rich , right to around 14 to 1 as that fuel vaporizes. Hold it there for a few, let it go.... and it stays rich, and gets richer as it warms.

 Guess, we spent around two hours on the Dyno ?   And I don't think the temperature read over 220F  taken at the base of the spark plug....... And that was when the bike was really ripping in the upper RPM's  for a sustained period . But as the RPM's dropped, so did the temp..... quickly and a lot !    And would settle in around the 170's . Some of that had to due with the richer AFR's of my bike. But most of it is from that oil pump and system.  I'm very impressed with it and the bottom end in general, which hasn't been touched.   So anyway.... you can see why the EFI is just relying on the temp sensor to "switch" when it reaches operating temp.  Above that operating temp , it varies to much.  Unlike a temp sensor in a water cooled car or bike, where the temp stays pretty constant.

That guy is tubby, and bag pipes are not aerodynamic. It's not mentioned much but Rollie Free had to set his aside on that historic day.

Hahahaha!     ;D   Well, that is definitely one advantage that I've always had on bikes.  With my metabolism I've always been on the skinny side, my wife calls me manorexic.  LOL  As far as that Guinness, perhaps a switch to scotch is to be had.  It's much more effiecnt when it comes to the buzz to calories ratio.    ;)

Don't you have an abandoned airstrip out your way that you can play on?  I might need to make a trip to Jersey.   ;D

  Oh ! .... I can find me a road Scottie. Come on out, there is still some country out west of here.  ;)  And we'll do up that Blackhawk too!!.... Be a Sweet Cafe bike for sure. I actually had to spend a little time... Ah... restricting it some  ::)  For the street that is !  It certainly is LOUD with that 1 7/8 header dumping that last hot pulse into the wide open Meggie.  A little to loud for the very decent gentleman in the next town over, who politely asked me to park that bike, in that bank parking lot. And walk home. And while your at it..... put on a proper helmet. very decent I would say !  And considering I have to ride through that town to get to work....

 I also just got back from weighing the bike. I stopped by a scrap yard and put it on there truck scale and it weighed in at 380 pounds in it's full street configuration.... I could go lighter. ;)

I'll always bleed Sox red and piss Bruins gold, but life is too short and I desperately needed a change of scenery.  8 months so far in sunny, snow free SoCal.  Best months in a long while.

  Glasshouse !?  he..he..he.   You have a good Eye. But no sir, close it's a Cj750 OHV. And I don't blame ya for missing it. They are a hoot to ride and built like a tank,oval framed, reverse gear, stone simple and reliable as a rigid pipe wrench......

Hi, fooled me I couldn't see enough of it. It is a beauty!  Seems I remember hearing about it before, you inherited it from your brother.
  Incidentally, those Chinese CJ HEADLIGHT RIMS can be made to work on a Royal Enfield using a 7" reflector. I have one on my G5 deluxe, & used one on my last Ural. They are on Ebay sometimes.
  Thanks for sharing!

 Thanks .... and ummmmmmm  ? That is a good idea . Instead of the "eyebrows" that slide under the outer ring.  I like it !  I may have to try swapping them , and see how it looks on the Enfield.
