>I have Yamaha XJ6 2012 and a throttle handle vibration problem
So I chugged internet recommendations and went to mechanic asking him to check spark plugs and caps (coils), and then do throttle body sync. He looked at me like I was a retard and asked to ride a bike.

After the ride he told me the bike runs fine, as for vibration, it's because my handlebar risers don't have dampeners on them. Then he showed me couple of bikes in his shop and handlebar indeed had some play to it, while mine was mounted rock-solid to the bike. (pic 1)

I checked my risers and while there is some kind of bushing around mounting bolts, it looks like very stiff plastic and not rubber. I use LSL short risers, but they don't change anything aside from using their own bolt. (pic 2)

Apparently there is such a thing as "Handlebar riser bushings damper kit" essentially a thick rubber that goes around riser mounting bolts and interfaces between handlebar and triple clamp so there's a little bit of play to it. (pic 3)

There are also dampeners that go around the bar, under the risers clamp like so https://youtu.be/H7ZE99rFTGE

So now I'll have to suffer until either arrive because nothing is in stock in my shithole.
