OK, I've been searching around and haven't found anything specifically about this, so help me out if you can. Recently, my belt started rubbing on the front sprocket. My Harley tech friend said that the swingarm may be out of alignment, but there's not much to do for it but put Armorall on the belt to stop the squeak. It works, but it's not permanent, and I think it's treating the symptom instead of the actual problem. Another friend said he thinks the motor mounts are going. He said to put in on the swingarm lift, fire it up and rev it to see if the swingarm bolts are moving. (I haven't had a chance to do this, since winter started here last week.) If those bolts are moving, is it indicative of failing motor mounts, or can they just be tightened? Or should I just replace the mounts and be done with it? | ||

I would check the swingarm isolators, swingarm bearings and axle bearings. I hope you have a shop manual and a parts book would not hurt either. Hope this helps. | ||

The swingarm mount block attaches directly to the motor, thus a rubbing belt wouldn't be any indication of failing mounts as both the motor and swingarm are attached and riding on the same mount points. The tuber mount does however hold the swingarm pivots. It is somewhat of an odd system and you'd have to look in there or have a service manual to understand what I'm talking about, but it is possible that the swingarm pivots have come loose in the mount block. They are somewhat difficult to check while they are on the bike, but each side has one which serves as a pinch bolt around the pivot. If the pivots are loose in the mount it is possible to have the swingarm drifting in the mount and thus cause your issue. Hope that helps and good luck. | ||

I've been doing a lot of research in the last few months, and what I've learned is that my rear engine mounts are broken. Has anyone replaced these? I friend of mine (who's a really good mechanic) has done it and says it's fairly easy, but it's about 15 hours of bench time. And yeah, you have to drop the engine. Advice? Thanks | ||

Lucy, by rear motor mounts I assume you mean rear isolators. It's almost impossible to have the swing arm and motor get out of alignment. The motor/swingarm can get out of alignment with the frame however if the rear isolators are hosed. If you friend is saying it's 15 hrs of rack time, you need a new friend or better mechanic. Sorry, don't mean to diss your friend, but it takes NO where near that long. The S3 frame is the same as an M2, I've done an M2 in 3 hrs start to finish. That was the first time too. I've done others since in less time. I'm in the area, in a NW Mpls burb. I could take a look at if for you if you want. If have time during the day I could look at it at lunch. I'm on 394 and 169. A quick look in person will tell lots. If time permits, I could also do the install (I have a crazy schedule lately and lots of "projects"). Not over lunch of course  The good news is the new isolators are MUCH better than the units in your bike. Much safer too if you have a failure on the road. Brad |
