Hi, I had copied a gearing chart last winter for cats but I can't find it. I tried to do a search and couldn't find it. Can someone post it again or tell me how to find one? Tom

Hi, I was looking for the chart with the different sprocket combinations and chain length and mph for each different combo. Some had a real nice chart posted last year but I don't remember which snowmobile site it was on. Tom

Don't know if this is what your looking for but i did a post way back on Tcat gearing for my sled and one of the helpful people on the messageboard supplied me with this chart for gearing and how it effects your speed. Hope it helps you!

Thats the one I was looking for, thanks for posting it. I was looking to go from 23/40 to 21/40 but I don't see it listed, won't that setup work? Tom
