Does anyone have a higher compression piston for there raptor, does it make a noticeable difference? is it worth the money, i want to do a couple more things to mine and would like to do them at the same time, i have a full exhaust system, i am planning on a filter and jet kit(any recommendations?), what else is a good mod for the raptor?

Also, does anyone know if i can buy the black and white plastic from Yamaha? I like my blue but not the nice white crease lines,

 

Just get in a Wisico 11:1 drop in,20 grams lighter then stock.It listed for $138. Should be a big difference I will let you know.

Go there and look for the fenders. They are like over $200 each though.

 

FYI - I've heard that you shouldn't go past 10.5:1 with the stock head. I'd talk with one of the engineers first unless you plan on getting head work done anyhow.
