A.T.V (4-wheeler) Question

Thanks for the replays
Yes it is a Suzuki LTZ400
I do believe it is the values.
Compression test when cracking is about 40psi (way to low)
When I checked compression well trying to pop the clutch I had 180 psi
I rebuild the bottom end of the motor in July of this year
I replaced all case bearings, crankshaft, connecting rod, piston and rings.

The LTZ400 has an auto de-compression thing on the exhaust cam so I believe that is my problem. I will tear it down when I have some free time & money
