a 13th front sprocket helps for power, but other than that cams are just about it.

You can remove you airbox lid and rejet the carb. But for sure your gonna need the cams, drz kit and a bigger carb with a different intake.

oh alright thanks man, i think im gonna stick with 14t sprocket tho just cause i like it better, but really dumb question tho, what all do cams do for you or w.e? lol

[kawi_rider_97]

they let more air and fuel in and let the exhaust gases exit faster

oh ok

warranty? if you touch anything on the bike it voids warranty now. doesnt changing the filter even void? if you want power youve got to at least put on a good pipe (not an el cheapo) and ditch the hair dryer stocker. if you still want more just swing for the fence and go to a 485 stroker with bigger valves even. killer mx motor

I suggest a FCR 39 off a 04 or yfz450 man what a difference with old style hot cams and a thinner gasket

nah i dont think so about about the air filter part, cause i put K&N on mine and jetted the carb and when i brought mine back into the shop cause i had to get a new carrier i had to tell them everything i put on it or did to it, and even if i did lie they coud just flip open the seat and see it themselves, but im pretty sure it all depends opn where you go and get ur bike and who ur waranty is through like either the dealership or the company itsself like yamaha or w.e
