heres mine !if you could get it to stay running i think a gamma 500 would dominate v6,v5,and formula 2 smoke. for instence 289 pounds 140hp .thats three classes you could alternate.almost bought one!!!!!
LWC - If you have lotsa cash... Ducati or Aermacchi 250. If you are poor, do your own R&D and need cheap donor motors... Honda 175. MWC - Ducati or Aermacchi 350 (I have a soft spot for Aermacchi) HWC - couldn't say. Gilera would be my pick but of course it wouldn't apply here with WERA Vintage since most of us couldn't afford one. V1 & V2 - Honda 350 V3 - Yamaha XS650 Couldn't comment on 2-stroke classes or super-vintage.
Oops, I forgot to give reasons why. The Ducatis and Aermacchis are proven winners. They've benefited from decades of R&D. The Honda 350's are giant killers. They can be made VERY fast yet relatively reliable. The XS650 is a strong runner and probably the most bullet-proof motor in vintage racing. I think that even the fastest one out there can reap major rewards by using a properly tuned exhaust (2into1 as upposed to the usual TT or 2into2s usually fitted). Last but not least... the Honda 175. I have yet to see one that was really properly developed but I think it can be the CB350 of the small bikes. It's advantages over the 250 singles are it's two cylinders with a 360 degree crank (which really benefits from a properly tuned exhaust), it can be bored to 240cc and it's ability to rev. It has a 41mm stroke and fairly small pistons which, theoretically, can rev to more than 14,000rpm's (rpm = power). I've been developing mine with the goal of eventually making power at those high rpms (13,000 so far) and although I haven't gone to the big-bore, it's proven itself against a lot of larger bikes.

thats an interesting selection.we got a guy that does research on his arimachi(?) that is the loudest thing on the dyno.arimachi art i call him benn modifying his for seven years or soo.
What wins in V6: most of the time a 86-88 1100 gsxr. Sometimes : a 89 fzr750 bored out to 900 something cc's, also a fzr 400 bored out to 410 - 560
