Thunderbike:

Although I have heard and read different statements related to a 3.5 lbs/hp limit (whether it's in or out), I think a regular Ap RS250 would be hard pressed trying to win a thunderbike race.

Here's some numbers:
340 lbs SV = 97 hp
410 lbs Buell or old F2 = 117 hp

Whatever handling advantage you may have over a stock SV or Buell is easily over shadowed by the lack of thrust and top end speed/power.

You could increase your chances by overboring, but then you've got to watch your motor for reliability issues, but it does help.

Speaking from experience (and being a heavy, mid-to-front of the pack racer), riding in the MW Sportsman class will be the most fun and the most rewarding riding a stock Ap RS250.  Hey if you're physically light weight, and you keep the bike tuned well, who know.

Good Luck
