I have a Raptor 700. The only thing on it (performance wise) is a HMF Sport series, K&N air filter, and an EFI controller. I want a little more *umph* from it. What would be the best thing to do to it with a budget of $1500? (shop labor excluded).
Maybe a cam or an oversized piston. You could also port and polish it. I think the 450s have more umph than the 700s. Maybe look into a trx450 or yz450
