I have a 2002 800 RMK with the 151" track... Geared down and weight added to the clutch - and it pulls awesome! I'm thinking about piping it, but am concerned that I might sacrifice my sled's dependability. Too often when out riding with mod sleds I see guys having to re-jet, check plugs, etc. I'm interested in a single pipe. Note that I am not mechanically inclined, I bought my sled to ride, not to work on... My riding is done at elevations between 4k and 8k feet... Any comments or suggestions?
