Late March last spring was my last ride of the season, unfortunately I only made it 5 miles and it crapped out on me. I thought I lost my crank, but could still pull the rope, and actually did get it restarted, but it sounded terrible. We towed it back to the trailer and while my friends rode I took a look at my top end and all was fine, I only had 400 miles on my new DD bearing, so in my opinion, since it sounded awful at idle, is that I probably lost a bearing or more in my crank. I don't have any pictures, and really don't have the know-how to feel comfortable fixing it right. What are the common problems associated with the crank on the 07 M1000's, and what am I looking at to fix whatever those issues might be? The sled has just under 2000 miles.
