  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.

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.

 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

  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.

    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.
