Re: Yamaha Raptor ?
Cool. I'd probably go with the Blaster myself if I were you. Otherwise if you had to have a 4-stroke(since many states give ya a hard time with two strokes now) then get the Kasea 250. It is a blaster frame. All the suspension pieces bolt right on from the Blaster. It has a v-twin 250 Honda engine (Rebel motorcycle), just re-done for off-road use. The only thing is it is geared too high.
If you decide to upgrade the Blaster, then start with the suspension first, then the motor.
