BMW Classic Racing Ponderings

Just had another weekend of classic racing on the old R90 (1000).
This is how I imagine I look when on my BMW.

Actually Andrew Stroud on one of the two Brittens that were running around the track.

Anyway some observations:
Machined down cylinders and pistons with a squish band work really well.
36mm Dells are a pretty good carb on a 1000cc
The balance pipe on the exhaust is not missed.
Norton mufflers are the best sounding mufflers.
The 308 cam pulls to 8000 RPM, I even on the cooldown lap out of interest did 1/2 of it in top gear, pull from 2000 to 7000 very smartly.
165 mains work with this setup.
Only have single plugs.
Ohlins s 36 shocks , emulators with .95 linear springs make for an awesome ride.
Nothing beats out pulling a Norton Commando racer from a corner then passing the bike in front on the straight, or passing any Brit racer on the inside of a corner.
Maxheadroom did about 3 races on it, seemed pretty chuffed.
Once Dirks cam arrives and get that fitted going to put the old BMW on the Dyno.

I don't think we've got an Auckland in Australia, or any Brittens for that matter.

The only pics I took all weekend were of the Britten as I was entered in 3 classes of racing, pre 72, open post classic and wait for it...pre war.
I was lent a bike to try out in the pre war class.
A 1935 Mk5 KTT Velocette 350.....yeah I had to Google it too.
Pic I took when I first saw it in the shed after not being out on the track for some years.

Pic from last week with Timo's tank he sent me

You need to put it on the dyno before you put the new cam in! No good saying ''Yeah, that's heaps more power!'' if you have nothing to compare it to.

good point but I can't be arsed traipsing up to Albany with it.
I'm only changing the cam so will be able to tell on lap times.
I might put it on the dyno when I get the ignition 'optimised" and maybe fit the 40mm Dells I have.
Its nearing the end of development as mid pack was my aim.

And so we'll all be still wondering if Dirk's all he's cracked up to be. Without concrete proof the bullshit will continue.
