250 / 350 bsa engines

Sounds like a plan to me!

Yes indeedy, a WD model to boot!

Well went fossicking through the porn draw and did indeed find the Jeff Smith did indeed think the B40 is a happy motor. Then I checked out Andy Robertsons B44, seemed a very happy motor and they were quite excited that Andy's bike hadn't cost 15-20000 quid ..... me too.

So b40 looks like a good thing, WM looks like the big end from B44 and i would say it is all a happy ending. Now all you need is a frame that reflects the B40s potential. ask Firko you may end up with a trackmaster or Hindall or something

Funny that Marc, I've already offered him my Sprite frame and tried to talk him out of it at the same time.
Am I correct in thinking that the WD B40 engine has closer scrambles type gear ratios? I seem to remember a conversation with some long forgotten old Beeza tragic who told me that the WD engines were a bit different and nippier to the civvy version.

Yeah when i was looking at what i had yesterday i found the WD models seem to use a mixure of gears from close ratio, wide ratio, standard and Victor (B25/B44/B50) gear sets. I kept seeing a few gears that had the 'V' and '57' stamped on them which means they are from the B25/B44/B50. When i get it down on paper i can tell you exactly.

It goes into details the different transmissions in here

If I remember rightly from riding one of my standard Army models a long time ago, 1 - 3 are pretty close with a big jump to 4th. I know the motor out of the Elstar had different ratios fitted with a more even jump between every gear.

cool a gap between gears for every occasion, still you only need 3 by all accounts/

the fella from the nsw bsa club I was talking to the other day was telling me pretty much the same thing, 1-3 are fairly close, and 4 was designed for highway/road use, pretty much superfluous for mx/trials

I checked the specs a few yrs ago (cos I knew someone w a WD engine) & likewise found a huge gap between 3 & 4

Cheers guys,

 He gave me a couple of leads and websites/forums to look at. He seemed to think, as a couple of others have mentioned that $300-ish was more appropriate as an asking price for an engine that needed rebuilding?

$300?!  I'll have 10 please.  Will you ship them?  Cash waiting.
