I run a 02 Summit 800x and i keep hearing stories about how the rings in my sled are shot. I have noticed a slight top end speed decrease. I need to know what the original stock compression is for this motor so i can test mine and see if i had a decrease. Thanks for the help. !!!

They are not all the same stock and break in can make a difference. Between 140 to 150 is what they test at new. If it is below 125 demand new rings or more.
