Hi Dan,
the timing mark on the pinion generally gets covered by the oil pump worm. You can unscrew the lock nut and you will be able to see the mark.
Happy Bulleteer-ing !!

Regards,
Tej

The pinion worm nut is a left hand thread. Turn it the other way to get it off.

For future reference, mark the pinion tooth next to the timing mark with a dab of paint while the worm is off!

Hi,
just wanted to check if anyone here using the 'S' cams has replaced the stock header on the AVL with a bigger one or is using one without the inner pipe which is present inside the stock header ( I am not referring to the hot tube which is towards the muffler end) but I notice that the AVL stock header is double walled.

Will replacing the stock one with a open/single pipe header improve things. I am already using the S cams and was wondering if the better header will further improve things on the bike.

Your inputs will be appreciated before I cut up the header and experiment.

Thanks

DanB

Hi TejK,

I don't think the pipe is double walled but there is that large steel ring at the head. I ground mine down by 2 to 3 mm to better match the port (used the washer as a template). My thinking is the more you can unrestricted things, the better!  Can't say how much better as I've done multiple things to the bike all at the same time.

If I recall a number of owners have done this, including BW and on the Harris Scrambler.

Finally got around to a test run (been traveling) with the new cams.

I should also note that I have a TM32 on the bike now as well, along with a few other winter mods...

First off, the carb: started with a 30 pilot; it was way too rich.  Put in a 27.5 and now it starts first kick(1.5 turns out).  Doesnt like any choke at the moment (its been 60-70s) here.  Think my 1/4 to 1/2 throttle is too rich.  Currently using a 190 main and a P6 needle jet.  Needle is stock, on the middle clip at the moment.  I fabbed up a cable from an iron barrel.

s-Cams:  Noticed nothing different (except a very responsive throttle and good torque) at the low rpm.  Noticed a huge difference between 2400 and 5000 rpm!  Same as Bill Harris, I hit an indicated 75 mph in fourth, around 4900 rpm (I have a cheap little digi tach; not very responsive).  I didnt get a chance to drop into 5th and go WOT due to traffic.  I need a good stretch of road to do my plug chops.  Again, I think im rich in the middle and have a few flat spots to work out.  I think the valves are quieter with the s cams.  They are not to tight and the cam lash was set very conservatively (not tight at all). 

Other mods:
- Hated the drag bars.  Didnt like the way the controls and master cylinder laid out.  Put the super bars back on.
- Dremelded the exhaust pipe at the head and took down that steel ring by a couple of mm.
- Fixed a couple of leaks on the gear box and primary; now have a small leak from the timing cover (new gaskets with a little sealant).
- New DID chain.
- Cheap eBay bar end mirrors that dont vibrate at all!  http://www.ebay.com/itm/7-8-Handlebar-Bar-End-Mirrors-for-Harley-Triumph-Ducati-BMW-Buell-Streetfighter/271251590982?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222008%26algo%3DSIC.MOTORS%26ao%3D1%26asc%3D21399%26meid%3D6350740824252992455%26pid%3D100005%26prg%3D9407%26rk%3D1%26rkt%3D6%26sd%3D350842841970&rt=nc

Very happen with the cams and carb.  Should have done this a while back.  Thanks again to BW for providing these cams!  What a difference.

Great news, Dan and thanks for sharing your impressions of these cams! They really are exceeding all my initial expectations and I am certain that, used alone on an otherwise standard machine, they would make a very noticeable difference.

There may be a way for you to get them in the future.
Do not despair!

I thought you got a set...?  There really is a noticeable difference and I'm thinking the next mod (over next winter) is some top end work at Aces just like 2CV.  My commuter bike really thinks it wants to do the ton.  ::)

Paul - Do you have any dyno reports of Stock AVLs? Maybe Asbo 11? before the transformation?

Armando decided he wanted a new tattoo instead of dealing with international exchanges.

Sadly, no - No 11 was in one day and pretty much out the next, with the cam swap and some other work done, but I remember the Hitchcock machine arriving with some work already done - carb, exhaust etc and giving power in the low 20's [about 23 BHP rings a bell]. It left here  with 33.34 BHP, not a bad increase and the cams played a very big part in that  ;)
 I don't think I would make a very good job of a tattoo for anyone, though  :o
