Im changing to Thar bars to get my bars as narrow as possible, this reduces my small inputs and a damper for just in case. No the bike is very stable. Im not....

Checked everything that moves? Wheel bearings, swing arm bushes/bearings, steering head bearings, fork tube bushes?

Anyone of those will cause a wobble, but for you to not have had it turn into something violent, I doubt it's a geometry issue requiring a steering damper. Which is not a fix, it is a mask. The original problem is still present.

No it is me. When I was younger I would crash bicycle because of it. Every now and then the Hornet will wobble a bit at speed. I have learned to get very light on the bars and it goes away. The damper is more of a mental thing to think it will help if needed. Narrow bars to help my movements from upsetting the bike. Ive gone from wide bars to bit narrower an the improvement is marked.

... Tyre?

On at least one street bike I've had a noticeable headshake tendency completely disappear on replacing the front tyre.

Wasn't even fukd for shape.

Yeah I had that on my Bandit, different thing. tyres on the Hornet are young as yet.

Well I can stop my tremor, large amounts of rum does it.

But then riding a motorcycle may not be my next best step.

I have chosen not to be a brain surgeon.

sounds like asuspension or bearing problem to me , i was gettign similar problems with my 600 repolaced the fork oill . seals. front springs and wheel/steering bearings + rear shock
and its great now, and that with ultra low/wide bars

Its not the bike. unless all my bicycles and motorcycles have had exactly the same fault. I get a little wobble at 160, I release the bars and the bike comes straight.

Does it happen when you're driving a car?

If not it's the bike. Some are just too sensitive to rider input, and you can tune a lot of that out.

No, not in the car. well it could be but small movements wont set up a wobble.

Thats why im setting it up with narrow bars and a damper. Narrower bars its got on help a lot.

Fair enough. Have you tried lifting the front on the forks, or dropping the rear sag a bit?
