Kolpin 90 2stroke wont start.
 

Hey guys I have a kolpin 90 that won't start has plenty spark and is getting gas so i was wondering Wat's the compression specs for these bikes ?? Any help would be great. Thanks

Welcome to the forums.

Good compression would be above 120.

Check out the Chinese section here for some great tips and advice.

Scootergptx ive been looking to try find a set of rings for the kolpin 90 but can't find anything but Baja 90 2 stroke rings. Any idea were i could find kolpin rings and top end

Chances are, they're the same motor. Most Chinese quads are Yamaha and Honda knockoffs.

As long as you have the right size, the rings should fit.
