[mike69]

Thinking of putting a kx 85 motor in apex. What will it take? Any advice and help would be much appreciated. Thanks

I would put the cr or rm before i would put the kx in it.The kx has the pipe coming out on the left side and alot of times gets in the way.

We have a kx 85 that my son races. Having 2 motors the same would make sense for parts. looked into some measurements and yes it will be tight. but has anybody done this mod? Cant find anygood info on the web at al
