Hey guys,
Is the amount of force necessary to turn over the motor a reliable sign of compression? I'm comparing a 99 polaris 600 to 2001 polaris 600 here. The 99 seems much easier to pull over than the 01. Could it be a sign that the compression is down in the 99? Or were they just easy to pull over?

Thanks

No.

Buy a gage (they're cheap) and get a definitive answer.

^^ thats the best answer to your question and ask for the compresion here or if ya have a manual check in there.

hard to pull over can also = engine issues eg seized piston, bad rod, crank and so on
