There is a guy around here with the name FFRracing (or FFRacing?), I believe he also races supermoto and he's got some impressive dyno's. Not sure if he'll share any secrets with you, but you might want to search for some of his posts. Hope this helps!

I thought you didnt need to do the BK mod becuase they solved the problems the 99 and 2000 models have in the 01 model? Maybe Im off track here!!??

Get your wallet out......question would you be willing to spend 1-2 grand to get it faster or buy a newer or new bike?

how about a falicon stroker crank? with ur current big bore you would then be pushing approximately 490cc. in my opinion, the bike is already understroked and then when bored it makes it even more. i would get the stroker crank. just an idea.

stroker, high compression, ported and polished, larger valves, ti valve train, NOS boondocker.com, menthnol, micro polish and blueprint and balence, If you want to go with a turbo or supercharger gice magna chargers a cal.. But you will need to do extremem modifications to the motor to accomidat those.

Yep, your off track.
Brian Kinny Tim ferrys mechanic invented the mod, and tim road the 426 in 01 or 02 one of thoose years. the mod can be done on all the 426, i think some were even doing it on there 450's.

the stroker crank sounds a good idea so will that work ok with the big bore kit ??
the head is ported and polished theres nothin more i can do in there its all been done
and i have a power now as well i forgot about that :cry:
