Hi there, I just purchased an 800r Summit 154 with 3600 kilometers on it. Sled was owned by an older gentlemen who used it primarily for trail riding and it looks extremely well cared for. I have heard some bad things about the 800R engine but for the price and condition of the sled, I figured I would take a chance on it. I'm not a "hardcore" rider and won't be pushing the sled hard. I am looking for things I can do to keep my engine running well without issue. I just want to have a reliable sled.
