well, i would like to use my b day money next year on some engine work, i was wonderin, what is the baest way to make lots of engine power, but stay 200cc and be AMA legal, I know they have firebreather kits but those run race gas, so would a +3 crank, some kennedy mx racing portwork, and maybe a headmod, with a airsol 200cc it. would that make some nice power?
