09 helix 150cc: zero compression
 

i Have 0 compression on my motor. looking for oem replacement jug and piston, or a big bore kit. what options do i have? also with 0 compression could this be a valve issue?. any help would be great. thanks

I have had a valve get stuck open and cause this. Pop the cover off and see if that is what you have. Usally bad rings will still give you some reading on a compression gauge. The other thing is if a valve gets stuck, it may be possible it knocked a hole in the piston.
