Hey guys. I've done some searching and could not find the answer to my question.....maybe some of you gurus can help me out. Just picked up a cherry 96' shee that still has the original top end and runs great but i was still concerned about the condition of the top end. I ended up doing a compression check and they read 100 and 101 psi. I know that is low, but I live at 5500' and know that it should read a bit low compared to sea level but how much lower? Is there a correction factor out there to adjust for high altitude or should I just slap a new top end on it? Thanks!
