New Buzziness

I have a 2012 650 adventure with 29,000 miles. I purchased it 2 years ago and have put 21,000 of those miles on it. I use it for commuting, IBA rides/rallies, and some gravel riding. For the past 1,000 or so miles it has become buzzy. Not something you can hear, more like what you can feel in your hands and teeth. The chain is adjusted correctly and just cleaned.

Any suggestions for things to look at. I am doing a bun burner this weekend and would like to get back to the smoothness it had in the past.

Thanks

Any new accessories been installed, have all bolts been checked? Be sure to check the bolts which hold on the front fairing assembly on the column neck, those have been reported to come loose.

Like Big B. said, probably an accessory bolt or a bolt on something you have worked on recently. Or... your engine is about to grenade itself. (Just joking)

I had a slow speed drop about a year ago and unknowingly sheared a bolt that held on the crash bars. I didn't notice any problem for a while but it manifested itself as a buzz at higher RPMs. I was able to diagnose mine by putting my hand on various parts of the bike while riding and finally I found the part with the extra vibration. Does your buzz happen all the time all the time or just when you are revving it pretty good. If it does it while the bike is stopped, you can more easily find the problem.

If it has engine guards, check those carefully for being tight. Then inspect the welds carefully for any cracks. The joint in front where the two halves meet is a common problem area for being loose and causing vibes. Different brands are worse than others (Givi).

No new accessories. I can't believe I did not think to check if I I had a screw loose. I know what I am doing tonight. Thanks

I only notice the buzz at highway speeds.

I have a 2013 Adventure that started buzzing on the highway (4000-5000 RPM) and it was a cracked weld on the stock crash bars. I "fixed" it with some tightly wrapped electrical tape until I replaced the stock bars with a new aftermarket set. Rev the engine into the buzz zone (or use a helper) and start feeling around the bars and body until you find it.

I did not find anything loose but will check the crash bars more carefully tonight.

Could this tire ware pattern cause it?

Valve adjustment? I have a Kawi friend that swears that handelbar buzz on his bike means valve adjust is overdue. He says its common on his bike.

Its just a thought. Others with more miles on our bikes here can agree or shoot it down. I only have 10K on my 2015 V2 and just did the valve adjust.

The valves are an interesting possibility. They were adjusted last about 3,000 miles ago. Beyond my ability to check. May have to take it in.
