trying to mod yfz 450

[sniper800]

any idea on what to get to squeeze every last drop of speed out of it

[Roody]

What have you already done?

[sniper800]

nothing but it is for a friend

First things are air filter, take off air box lid, and new exhaust. You will need to re-jet the carb after making any of these changes.

ok

Drop a couple teeth on your front sprocket and get like a 12 tooth sprocket

[quadmistr_2010]

that would make it super torquey.. if you want top end add more teeth, like 14.. but easier wheelies with a 12..
