Throttle hand getting numb?

[Coach]

The rope has helped some, but I want to fill the lower portion with BBs to see if doing both helps even more.

Coach, I'm wondering if maybe you should look at the bike itself to get rid of the vibration problem. My girlfriend's '01 Vulcan 800 Classic is s mooth rider but gets buzzy every once in awhile - I cure it by lubing and/or adjusting the rear chain. Maybe you could do that and also make sure the wheels are still in balance and do a torque check on all the engine mount, handlebar and footpeg mounts to make sure nothing has come loose which would cause vibrations.

Mine has a brand new chain and sprockets but I will check out the other stuff just in case. The things is, it was smooth before I changed the handlebars.

Is it still smooth if you put the old one back on? You didn't, you know, go and drop the magical anti-vibe piece on the garage floor or anything, did you?

Bars can make a big difference in a case like this. Changing the overall length or diameter or tubing thickness can change how any bar vibrates in response to the same engine vibe patterns.

When I swapped my "tricycle" bars for CityX bars, there is an added crosspiece. The net result is that the bars must flex less, so more vibration is transmitted to my mirrors. A lot more.

I have a pair Kuryakyn ISO® Grips on my Virago 1100. Now that bike has vibration issues, lol, but those ISO grips are great. I believe they also have a throttle rocker for them as well.



But this might actually be a throttle lock???

The iso-grips and throttle boss shown above help alot, as does this:

I have a simple throttle lock that I slap on when I go on longer trips so I can rest my hand. It works.... and it's a little safer than riding with my left hand on the throttle.

I have a feeling it's just the difference in the bars. They are totally different. The old bars were the stock buckhorn style bars that attached by bolting them into the risers which bolted to the bike. The new bars are drag bars off of a Vulcan Mean Streak and get bolted directly on without separate risers. So they are slightly lighter, definitely more rigid, and no longer have the added mass of the risers in between. I'm going to try the BB idea tomorrow.

I personally believe it has to do with the vibration and hand position affecting the nerves in the carpal tunnel.

carpal tunnel
n.

A passageway in the wrist through which nerves and the flexor muscles of the hands and fingers pass.

I find that this happens to me most often if I am gripping the throttle too hard . I have a throttle rocker around here somewhere that I am going to use to try and see if it makes any difference .
My risers and bars are rubber mounted and I have little vibration . So I keep thinking that it is me or something that I am doing that I can change .
Kind regards, Wizzard
