I need someone a lot older and more experienced to help me... i was checking out cycleworksracing.net. I found that i can bore my motor .40 over, but i want to do this.. with also the cwr air filter kit. What else would i need to do if i wanted to bore it .40 over and still be able to race in like the 350 class or w/e?!..

i dont get it .40 over wont knock you out of the 350 class if you got a 250 but what does the air filter have to do with it do you even have a pipe yet

well .040 will only increase your CC's by like 4-6 if that, and you will need a Piston, and the air filter will help too, and you will need an aftermarket exhaust to help it out as well

I don't got the exhaust or ne thing yet. But i was looking at probably WB.. anything better out for full exhaust on Mojave?!?!

white bros sucks ! any thing but them please

but definetly get an exhaust and filter (K&N) then rejet your carb also new tires (razrs) and they will will probly require you to have nerfs and a killswitch to race
