Rattle / buzz noise at 6000 rpm after wire harness recall

Has anybody noticed a noise probably coming from the front housing at around 6000 rpm? In 3rd gear at 6000 rpm is quite noticeable. This started right after the recall work, so I suspect the dealer's mechanic left something not properly attached. It sounds like a metallic or plastic vibration. I'm taking the bike back to the dealer tomorrow. I couldn't find a thread about it. Thanks!

My bike didn't have wiring harness recal but I had the same problem. The only thing I messed with was front dash. Removed it many times, installed some wiring inside it, later one relay, then adjusted front light hight... The buzzing noise appeared a year ago. I got crazy trying to find a source. Opened the dash again so many times, changed all zipties, rerouted all the wires I installed. No joy, buzzing persisted. Then it simply disappeared one day without me touching anything.

Thanks bosnjo. The dealer explained that the recall work involved the harness reaching all the way to the ignition key assembly, which is right there underneath the dash. Tomorrow I will tell them to check that area. They said that if the problem was of their doing they would fix it at no cost. I have little hope. Thanks for the tip.

That's one of those things that could be very difficult to locate, since you can't probe around while your bopping down the highway. Could just be something like a cable or connector that got slightly displaced and is now buzzing against a fairing, frame, or trim piece. And if it's in an inaccessible location... Good luck, let us know if you figure it out.

Do you have crash bars?

I had the same exact symptom on my Glee "adventure" with the stock crash bars. I finally tracked it down to a cracked weld in the bars. I taped the hell out of it with electrical tape until I was able to replace the bars. No more buzz.

If you have bars, and they're not cracked, maybe the dealer didn't tighten the mounting bolts completely. If you don't have bars...Well...Keep us posted.

I took the motorcycle to the dealer and after a day's work they said is the Givi crash bars. Specifically the left one. Possibly something shifted when they did the recall. They went through the wiring harness connectors, added tie ups, checked padding on plastic pannels. Eventually the mechanic test rode the bike, noise still there. He pulled up the left bar while riding at 6000 rpm and noise abated. At the shop he tried to shift the bar down a bit. Less noise but still there. I may remove them and offer them on ebay.

My conclusion is that, if the Suzuki bars don't buzz, maybe Suzuki is testing their design to make sure they don't. Maybe Givi designs these bars for the Vstrom 1000 but do not conduct enough testing. Just speculation.

Dealer did not charge for this work.

Bosnjo do you have Givi crash bars installed?

I have the Givi with no buzzes. I'm assuming that all the mounting bolts were checked for tightness. If you have that plastic piece that clamps around the bars, did you check that?

Good point G-Dub! I'll check the plastic piece.

Yes, I made sure all bolts and nuts securing the crash bars were tighten to spec, using a torque wrench.

Just remembered what happened on my friend's 2015 Veek with Givi bars. He had very strong buzz on 5000 rpm. He did lot of testing and he found out it was the left bar. He'd simply grab it with his hand on 5000rpm and buzzing would stop. He came to my house saying he checked all the bolts and everything was nice and tight. Then I came up with different idea. We've loosen all bolts in order to have the bars relaxed and just then tighten them back. When I was unscrewing one of the last bolts (or nuts, I can't remeber), I heard big "clonck". The left bar has moved. Then, after making sure all of the bolts were loose, we tighten back everything and he's never had the buzzing again. My case was different, but on his bike it was as explained above.
Try that approach.
