If it is something you want, then Wintertime and I can walk you through what you need to do to make it a house puller. Snowest forum has massive amounts of very good info on the 05 900 to make it a reliable beast. I have an 06 RMK 755 which is basically the same motor but a bit smaller. The vibration is way over talked about and many ways to deal with it if you want to. Check out snowest discussion forum. you have to join it with a small fee. well worth it for the info on that sled. You can do all the updates and a few extra things for under a grand. First off check your carb boots for cracking, you should pull muffler to get a real good look. that is a major issue with the 05, 06 755's and 900's. I have never heard a sweeter sounding motor than when you add the SLP can to it.
