TERRIBLE Day!!! AHHHH!
Greetings fellow Desmo enthusiasts,
My day yesterday started off like so many other perfect riding days. wake up, roll out of bed, step outside to a 72° 30% humidity day, here in New England, the perfect riding day.
After taking a cruise about an hour away I am cruising through a small town when my 09 Monster 696 with 30K miles make a single mild pop and shuts off. After finding a safe quite place pull over I hit the starter once to hear the lack of normal thump thump as the pistons build compression. My first thought was oh god please tell me I didn't snap a rod, but given the smooth rotation of the starter and a lack of any crazy noises and holes in the jugs or block I ruled this out.
My next thought was what we are all most likely thinking at this point, timing belts. I pull out my toolkit and pull off the horizontal cylinder belt cover to find a shredded mess of what used to be my timing belt.
After getting the bike back home to my shop I pulled the vertical cover off (I had to break this one as the threaded insert got destroyed when the belt let go). what I found surprised me, the belts not due to age or miles (I am very religious about the maintenance of my duke), but the fixed idler pulley on the vertical cylinder came apart. I found the pully pushed up against the block with its ball bearings scattered inside the belt cover.
Where I am now, well we all know where I am now, up s*!t creek without a paddle and no bike! My question to the group and what I hope will spark some conversation is this. What are the logical next steps given that I'm not going to get rid of the bike? Parts I can order, labor I can do, time while always at a premium I can find, but what are the things I should be thinking about at this point?
I imagine that I should be taking the heads off and sending them out to be inspected and more than likely rebuilt. I will be replacing all of the timing belt components minus the pulleys, I don't need another idler failing on me. From what I can tell with a flashlight and my eyes, the pistons do not appear to have any damage from the valves but this will be investigated further when the heads are removed.
Any thoughts, comments, stories anyone has would be greatly appreciated!
