Andrew, As of now I plan on being at the next event. I have no endurance ride so I am going to sit out all of the saturday races. Too many mixed classes IMHO. Not a desirable condition on an under-powered bike that needs to hold corner speed, so looks like 500GP, Open GP and Eurocup on Sundays FIM races.

As far as the lift kit, $150 seems fair.

You seem to have some cool bikes Birdman. Got any more details on them?

Here's a shot from a couple of years ago.

Couple of my bikes that I race mostly with the USCRA and a few AHRMA & VRRA races;

R50/5 on the left. 500GP(USCRA) and Sportsman 500(AHRMA). Engine lifted, raised, moved forward. driveshaft spacer, backbone brace, heavy bracing around frame stem, High CR J/E pistons, heads mildly ported. 336 cam, Luightened flywheel, Straightened intakes running 32mm Mikunis, PVL ignition, MG Lemans 1 chin fairing, 18" rear rim laced to front hub, Hubs lightened front and rear, Dropped upper triple tree brace (Luftmeister I think), additional lower brace made from lower triple, stock front brake arc'd and lined by Vintage Brake. Works Shocks & HD springs up front, 5spd tranny, Ugly stepped exhaust with supertrapps.

R75/5 on right. Open GP(USCRA) and BEARS (AHRMA). High CR Venolia pistons, lightweight gudgeons, CC Products stage III heads, Dual plugged, 44mm intake/42 exhaust, 336 cam, 38mm mikunis with pods, Lightened flywheel, Grimeca 4LS brake set up by Vintage Brake, Dyna ignition (total loss), big tube swingarm,19" front/18"rear, upper and lower fork brace, cable actuated rear brake, Homemade F1 type exhaust canisters, Luftmeister bolt on lateral braces, Works Shocks & HD springs up front, Ducati 750SS fairing. Undergoing mods to lift engine and graft Post 81 tranny. Hope to install PVL over winter.



Not mine, but I get to swing a leg over this occasionally ;
It's a R50S in a /5 frame. Its a joy to race but we had plenty of trials and tribulations along the way. For more details see www.barringtonmotorworks.com/, Motorcycle Gallery/Race bikes/Willie II & III. Hope to race it again next season.

Very tasty, thanks for posting, more inspiration for my 500 project. Does the 500 run stock sized valves?

Laugh Better.

The bike now has borrowed Dellorto 32mm carberators. Also new exhaust headers and silencers. The bike was a LOT more competitive than it was before. Bings may be alright for the street, but they don't work very well on a race track. I was more than 10 seconds a lap quicker with the Dels.

Like I always say, Bing's are great carbs if performance is not a concern. Now you just need bigger Dell's for even better performance. More than likely, bigger Dell's or not, you need some long velocity stacks and some longer carb spigots. Set up right, they make a big diff!

I agree. Last Tuesday the decision was made to get the bike motor back together and race on Labor Day. The Dellortos are on loan to me. I didn't have much in the way of spare components. The idle jet seems to be completely wrong. The needle jet could be improved. And the main jet was a 124. No stacks available this time around, but I will get some. Another racer gave me a source for stacks. Very fortunately for me, Street and Competition - a vendor at the track, had some main jets (130). These improved the bike's power noticeably from the morning race to the afternoon. With the 130 jets I was able to keep pace with other BMW bikes running 860 and 900 cc motors. Mine is 750. This was a very significant improvement in performance over the Bings.

I wouldn't be surprised if 130's jet the best. I have 130's in my 38mm Dellortos on my R100. My R65 with 32mm Bings jet for best power with 130's too. 130's to 140's are usually it. With 125's in my R100 it feels like you hit the kill switch at a little over 5000rpm in top gear.

Beemers tend to like LONG stacks. Like the late model airbox has, for instance.

I put together a video from the racing on Monday. I hope it shows the improved performance of the bike compared to earlier this year...

nice bikes!!! Do you know who the manufacturer of the chrome pipes is? Regarding the PVL ignition, do you anyone that makes an adapter to fit the PVL to an airhead?

My bike was in the BMW Riders Association's magazine, On The Level. November 2012 issue. Pages 54-60. It looks great in glossy!
