I've got a 08 R-1 that just started smoking last time we raced it, my son got it to 280 degrees in Dodge City over the 4th of July, melted the stator, I replaced it has run good since then.So I decided to do a compression test on it last weekend before I put it away for winter #1 cyl 165, #2 cyl 155 #3 cyl 162 #4 162, I shot a little bit of oil in lower cylinder next test it shot up to 180, obviously ive got a ring problem. Two guys that we race with that I trust there opinions said to rering it or get another motor, which I am planning on doing. My question is how much variance should there be between cylinders before I become concerned? And also keep in mind that we are at 5600 feet elevation were it was tested at and raced not much lower than that, is there any kind of corrected formula for figuring out what this motor should pump up to (if it was healthy) here at this altitude vs. sea level? I know a lot of guys say they should hit somewhere between 180-200psi? Is it because of altitude that my readings are so low or is this thing just a sick pig? Thank You In Advance! Dave
