Alright guys, I need some diagnostic help here. While riding my '00 M2 today I noticed an intermittent squeak soming from the bike. It would happen both under power and coasting down in gear. The sound most closely resembles rubbing smooth styrofoam together, with the under power squeak being about two octaves higher than the deceleration squeak. I think I narrowed it down to the output sprocket from the tranny, but I can't figure what would be making the noise. AS I said it was intermittent with no discernible pattern to it's coming and going. The only that has happened recently was the oil filter spinning off and blowing oil all over the bike while riding. It soaked the entire bike from the seat down. Does anyone have any idea what could be causing this? I didn't notice any performance problems, so I'm baffled. Please help me figure out what this is. It was so loud that the guy IN FRONT of me could hear it over my pipe (D&D) and ear plugs. I do not want to have to put up with this forever. Thanks for the help guys. Greg | ||

sometimes i hear my belt squeaking when i push my m-2 out of the garage but not while riding. pipe is too loud! hope it's not the dreaded bearing behind the pulley. | ||

Not to be alarmist, but I would get the seal off the inside of the front sprocket and look inside that 5th gear drive assembly (both of you!) ASAP. You will need a new seal to replace it as you will have to punch a hole in the old one to get it out, but once it is out you can look in there and see if the bearings in that 5th gear drive assembly (what you are looking at) are rusted or otherwise look damaged. It would not be totally unusual if they were. You can also pull the tranny (believe it or not it is really not that hard) and inspect from the other side. I had the exact same symptoms you both describe. I ignored them and increased the cost of my eventual repair by about $300. | ||

Well I discovered the culprit after some closer inspection today in the light. I had one of the rear pulley bolts back out and machine a small arc in the swingarm. I'm lucky that's all that happened. It could have been a lot uglier if that bolt had caught on the swingarm. That's my second lucky break in the last two times I've been riding, maybe I should take a break, eh? |
