compression for a 900

[cgsleds]

does anyone out there know what the compression for a 2006 900 is?

not to sure what peek is but you want any thing from 120-130 at least , mine is sitting at 120 both sides. the compresion on its self is not the main concern, its when the sides are uneven say 130 and 100. that is when you have a problem.

I have 125 on one side (mag) and 140 on the PTO side.
Wondering when I should rebuild?
It still performs great. About 1900 miles.

these things are notorious for running the mag cylinder lean. most piston failures are on the mag cylinder.

you can probably get by this season, i would pull the plugs and check the piston wash, maybe pull they y-pipe and take a look at the piston through the exhaust port. check for major scuffing.

might add a fuel box and add about 2-4% fuel to the mag cylinder.
