Like what happened to Jay a while back, at some point during the Forney ride yesterday, the bolt holding the "chain keeper" part of the Xstream crossover idler vibrated loose and came off -- I have no idea when, but I'm surprised I didn't hear the chain rubbing against the arms at some point. When I got back to the parking lot, I noticed the assembly was gone.
The IDLER was still there, obviously, but no one in the group saw the piece fall off, so I had no idea where to look for it. I noticed that even one of the 3 screws holding the idler together was starting to back itself out, as well.
Not quite thinking clearly, I put the bike on the roof rack, and drove home... and on I-30, heard the crossover idler fall off and hit the car roof as I drove into the gusting winds... and saw it roll off somewhere off to the side, but there was so much traffic I couldn't stop or really even pull over.
So, I'll be ordering a new idler assembly........
