I noticed that I have 21/41 T sprockets in my 800. I think being that this was a Utah sled, it either came from factory like this or was changed, as I believe they came with 19/39 T.

I have put on twin pipes, jetted, etc. for my altitude, and per SLP should also be running 19/39 T sprockets. I know I would lose top end, and gain bottom, but would the difference be significant? I don't want to spend over $200 to repalce the sprockets and chain, if the difference is minimal.

I would think that much tooth change would be huge, but someone with experience would know more.
