Had a fantastic time up in MV this year. Unfortunately, on the last day of the GTG and on the way home back to Fl., I noticed an odd sound coming from the motor while in gear and moving. The bike has been in the shop for over a week now and they seem to be having a difficult time isolating the problem.
I figured if nothing else, I'd post the symptoms as best I can and may be one of you might be able to offer some words of wisdom...
The sound I'm hearing is very subtle. It is like a cricket/grinding sound, very faint when the bike is engaged and moving at speeds over 30+. As the bike moves faster the sound level increases. The sound has a frequency component to it. The frequency of the sound also increases as the speed increases. When the clutch is pulled in the sound goes away.
Also noted is when the bike is cold and I start to more out, when the throttle is twisted and then released there is a squeaking sound I hear coming from what I think is the front lower part of the motor... After a few minutes of riding the squeaking can't be reproduced... until it's cold again.
The motor itself seems to be running strong. Sounds great otherwise. Lots of power and seems fine otherwise. Not being a wrench myself, my troubleshooting skills are very limited... however I can't help wondering if this isn't either a clutch, tranny or drive train issue...
Any of you mechanical aces have any suggestions or ideas..? I'm absolutely bummed having my SERG outta commission for this long.
TIA for any suggestions -Matt
btw - 09 SERG pretty much stock except for basic exhaust upgrades and TTS.
