Hey all,
so I recently found the compression on my '89 Polaris longtrack to be 120/60psi.
I tore down the top end and found one piston damaged. I called the Polaris dealership and was told they don't make those parts anymore. He did say that I could bore out the cylinder and put in an oversized piston on just the ONE side which seemed strange to me. When I asked if I'd have to do the other side he said no, just the one and that it wouldn't make a difference. Can anyone confirm this? Also, how would that work cause the math to me would be inproportional per side. He claims it doesn't matter as long as I'm within 10-15%. I have my doubts and think I should just save myself from grief and do both sides but it's twice the price. Any thoughts?
