I just purchased a 13 RMK 800 that has known top-end issues. I am going to start tearing into it and I know that there have been many many others that have gone down this road. So I don't have to reinvent the wheel, is there anyone that has done the homework on this and might give me some pointers? I have read that it's best to replace pistons with the 2015 pistons not the 2013's? I want to get the cylinder refreshed, is there a company out there where I can send mine in and get it done? I spent a couple hours yesterday looking for info but I feel confident that someone has already done the research and can help me out. Any threads someone can point me to?
