2 stroke compression

[jeepthing07]

friend has a 1993 polaris 350l 2 stroke. engine wont run has spark and fule compression is 60psi. what should compression be on a 2 stroke?

[soyo]

call a polaris dealer and they will tell you what it should be on that model. but that is way low, im thinking 120psi

We got it tore down.. edges of the piston got hot and started melting/cracking off scored up the walls pretty bad and the rod bearing is toast.

Can you put a 400 2stroke in a 350l? they look the same

[headache]

stock compression should be around 120psi.
