Compression

Can anyone tell me how much compression my 2002 Grizzly should have when checked with a compression tester?

If the manual I have for a 660 is covering a 2002 its 188.31 psi) at 850
r/min. Thats using a stock piston. 9.1 : 1 compresion ratio

Might be a little dust on the Grizzly
But it only gets better, one piece at a time. 98 600 Green Grizzly. 27" ITP MudLites, EPI Clutch Kit, UNI filter, DynoJet kit - Stage 1, HMF exhaust .Murderfied cooling fan motor.
30 year old Simpson's Sears 46" Plow, crappy little winch. Fabricated harness . . .

Is the info 'cause you're checking to see if a rebuild is due? There's a TON of threads out there covering that topic...

Collecting some information before an important decision needs to be made is always a wise course of action!
