Just bought a Apex MXR 90. Going from a very fast polaris predator 90(that the frame busted more times than I can tell you) to the apex. Need to make it faster! Any suggestions? Has anyone done any mods to these quads yet?

 

Polaris & Apex motors are essentially the same. The biggest mods are going to be porting & clutches. They come with a decent pipe & good carb from the factory. Ours is pretty fast - just cant keep a set of gears in it.....

 

Westcoastquads has mods for you.
