[bosshogg1]

i told my friend about a big bore kit for his quad than i was talking to another guy an thought he shouldnt mess wit his motor he should do hotcams jet an new pipe can sum body give me sum input

the problem with the big bore kits is they take away from the reliability of the machine. simply boring and porting and polishing the motor is a big improvement from stock and a hot cam is always a good decision. i bored mine 60 over and ported and polished it. i added the hot cam and a slip on pipe and jet kit. now its a little picky about coldstarts, but doesnt break down on me, its just cold blooded more than it used to be. stock is the most dependable without a doubt, but if he want real power out of it, the big bore kits are readily available, just take a toolbox every time you ride, just in case.
