Odd Vibration/buzz Around 2200 Rpm

Hi there, wondering if anyone has come across this - a sort of high pitched buzz that comes occasionally when passing through around 2300 rpm. I captured it on video here:



PS it's not the windshield as I still have the sound even without the windshield. The only things I could figure that maybe buzzing is that the fender seems not stock - has a longer mudguard, and that the old owner put in a custom LED headlamp so maybe the casing is buzzing?

It's a bit unsettling when it happens!

Thanks in advance

Hi there, I believe I have experienced the buzz in various gears, 1st to 3rd, and seems to be in lower speeds when the engine is pulling a bit...

 

I will try on the centre stand. I have taken off the mudguard and out some foam on the fender mounts and thkughtmi had it solved but it still happened , but seems less frequent.

 

I think I may got it figured out. Along with the crash guards installed seems to be a skid plate under the bike. I can feel it vibrating as I turn the throttle that rangez and tapping it does seem to emanatentuat soundm maybe I can stuff some insulation foam or something between the skid plate and the crash bar... Or is too close to the exhaust? Any thoughts?

Wonder if the skid plate can be taken off but leave the crash guards on. Skid guard also makes changing the oil filter a pain...

Success! I wedged some rubber tubing in the gap between the skid plate and the crash bars and the noise is gone - what a relief! Eventually I think I'll take off the skid plate
