Compression results..
Okay.. I've been researching compression test results everywhere on google.. most people on the xx range from 80-100 , doing the test with just ignition of starter and with the dial plugged in.. I got almost if not 90 psi .. is that good or bad? I really don't care if I have to rebuild it .. rather rebuild it now than do further damage.. I let a buddy drive the xx and he thinks it was a rocket and works really fine.. I can't really tell if its lacking power cause I am use to my skidoo and streetbike.. but it seems to run fine

After heating up the motor the manual says open the throttle all the way and turn it over till it reaches its peak. According to the manual you should get about 65psi due to the auto decomp that is on the cam. You will get a higher compression if the motor is cold. Warm it up and try again.
