Right now I have an 01 yamaha warrior. That performance wise is stock. Waiting to pick up an alba pipe and fmf header in the near future. Anyways.after that I was looking at a big bore kit from powroll the 365cc package but then I saw the 430 cc package and all I want from my quad is more perfomance make it have better throttle response and have it wheelie better and was wondering if the 365cc kit will do this for me or would the 430 be better? Please do not tell me to get a new quad I dont want one.

 

It depends what you ride on...if you ride on tight trails and some nice straight aways do the 365, but if you have like all jumps and what not go for the bigger one.

 

i would go with the smaller one just to keep the heat down where the warrior is only air cooled

 

I would with the 365, because as cam said, it's air cooled and you may overheat your motor. But if all want to do is drag race, get the bigger kit.

 

Is there a kit in between them like a 405? Maybe you could get something like that.

 

There all kinds of kits right now, like the alba 400 stroker kit. It's pretty expensive though.
