Looking at 2 1998 ski-doo tundras to buy for the kids.What should the compression be around.

I have a 96 skidoo formula sls 500. It has 155 on one side and 165 on the other but supposedly thats pretty high compared to usual. I think most sleds are around 140 but I'd double check with someone else because I only remember that from reading forums a while ago.
