Hey just wondering if anyone can answer a question on my Yamaha for me? I have alot of oil smoke from the muffler and even have oil splattered on my rear plastic from muffler. I just got through pulling my spark plug and checking the cylinder with a compression tester. I got 102 psi. What is the minumum I can have? I don't want to pull the motor yet if I don't need to. Is it possible that my problem is the valve guides?
