While out riding yesterday I heard a "tinging" noise upon acceleration. It wasn't a steady noise, no continous pattern, just an irregular "ting" upon acceleration. I first thought it might be the primary chain loose and hitting the primary cover (although the adjuster is automatic), then I thought maybe it was the "Tommy Gun" exhaust cover rattling (although it sounded like the noise was coming from the left side). Any ideas or similar happenings?

 

Use only 93 octane. Sounds like engine detonation.

 

Thanks for the quick response Graduate...I do use only 93.

 

My last ride back in November I got some louder tinging during acceleration. I pulled into a parking lot to check it out but couldn't find it. Sounded terrible. Checked the oil and decided to take it easy on the way home. Later found that the exhaust bracket had snapped in half. Whew!

Chased another noise a couple summers back. Had several friends and mechanics test ride it. No one could pinpoint it. Turned out the the rubber sidestand bumper had rotated on the frame and allow the sidestand to intermittently contact the frame.

Hope you track it down and it turns out to be minor.

 

Headed out to the garage to go over the Fat Bob and bringin' my fine tooth comb.

 

While your combing it's hair, you might as well give it a perm.

I have had the problem with the rotating rubber piece on the jiffy stand. Makes a pretty good clank when hitting bumps.

 

Will do

 

Maybe it was your Gremlin Bell snapping back against the frame.

Did it sound like this:

Ting, waaaaaaaaaaaaaaaaaa! Clunk, ting waaaaaaaaaaaaaa!

 

Good one, Topspin. But, I don't have a Gremlin Bell...maybe it's time to get one.

 

Some additional info: I could be accelerating, then open the throttle a bit more to increase the acceleration...then the noise could be heard.
