kvanderstel 0 Posted September 2, 2013 I've picked up this vibration that is definitely engine related. I feel it all the time but gets more rhythmic as rpm's increase. I have yet to check engine mounts, I'll do that soon, but are there other internal things I can look for? It runs great, no weird noises, nothing. Ok, one thing, I swear, the sound of the engine seems...... Muffled? Maybe I'm dreaming. This engine has counter balancing right? Could a broken clutch spring do it?

paulmbowers 236 Posted September 2, 2013 A failed muffler will cause all those symptoms. I had one fail internally. Share this post Link to post Share on other sites
Suspenders 43 Posted September 2, 2013 I vote motor mounts. Share this post Link to post Share on other sites
kvanderstel 0 Posted September 3, 2013 I vote motor mounts. Well, both are easy to check. The muffler theory will require that I bother the neighbors a bit, but it shouldn't take long :rolleyes:/> :rolleyes:/> :rolleyes:/> Share this post Link to post Share on other sites
kvanderstel 0 Posted December 22, 2013 I took the clutch assembly apart, and I noticed the helical gear ring on the back of the basket is a bit wiggly. Is that the cause of my vibration? Share this post Link to post Share on other sites
TrophyHunter 15 Posted December 23, 2013 Is the part in THIS pic? Share this post Link to post Share on other sites
kvanderstel 0 Posted December 23, 2013 Is the part in THIS pic? Yes, item 1 in the diagram. It gear ring has helical cut gears and seems to be riveted on, does not look serviceable. But it is loose, I would figure the gear should be fixed tight to the basket.... Share this post Link to post Share on other sites
TrophyHunter 15 Posted December 23, 2013 I'm not a certified mechanic, but I can guess something manufactured to be solid - riveted - should remain that way. There's a lot of stress right there and if it's not solid, I think it's probably the source of your vibration. http://advrider.com/forums/showthread.php?t=61568 <-- this thread may have some answers, too. If new parts are hard to find or not budget friendly, somebody here might have a good shop to take it to for a re-riveting if it's not too far gone? Share this post Link to post Share on other sites
