I have an 07 600 RMK 155. Snowchecked it new, I now have 7300 miles on it, never been opened up. The only issue I had with it was the delaminating carb boots, check them every year, replaced them twice now, other than that issue, no problems with it at all. It has been a great sled, I get out west about once a year with it, and I haven't been left behind by my buds with the larger cc sleds. It may take me a pull or two to get up there, but I always do. Hoping I can get a ride on a Pro 6 when I am in Tog the first week of March, of course, that might be a 10,000 dollar demo ride. LOL.
The build Jonce did is awesome!
