Unhappy Looking for Vibration Solutions

Yesterday I rode about 70 miles on the interstate highway at about 70 mph on my V-Star 1100 Classic and by the time I got off the bike, my hands were tingling and numb. The discomfort was so extreme that I would rather not ride the bike at interstate speeds in the future unless I can find a way to reduce the vibration.

The bike has Kuryakyn ISO grips, so adding Kury handlebar weights is one possibility. Anyone have any suggestions?

Thanks and ride safe.

I've never had this problem. How many Miles? Have you done a plug check at high RPM. 2-5 minutes at high rpm (70-80 mph in fifth or slower with high revs in a lower gear). Hit your kill switch and pull in the clutch. Coast to a stop. No Engine breaking. Check plugs for color. You may have a cylinder not getting enough fuel. I have read some posts and articles about timing getting off, how that happens is beyond me. Camchains usually don't slip. Another thing to check is TPS (throttle position sensors) on the carbs.

I would add the grip weights. The factory put the weights there for a reason. I get the same tingling in my right thumb after extended high speed runs, I never replaced my bar weights. Gel pad gloves seem to help also.

I always wondered if MC tires get out of round from sitting for several months like car tires.

They most certainly do, I notice it almost everyday mostly during cooler weather as slow speeds. This is just after a day or so of sitting. Radial tires don't seem to suffer as much as the bias ply tires that we have on our bikes.

Out side the box

Riverboy,

When I had my 1100 I did notice vibration in the mirrors a little above 70 or so, but I never felt any discomfort from it. I have read some of discomfort problems come from posture. We sit leaning slightly forward with some weight on our hands for long periods of times. The handlebar weight thing makes sence though.

You would know though if you did not get the same feeling at lower speed for same amount of time. I get a pain in my neck on long rides with my Liner. Risers helped.

Lightbulb Thanks For Your Help

Thank you all for your suggestions. I pulled out my shop manual and looked at information related to mechanical issues, dug through internet information, and checked out the commercial solutions as several suggested. From the various V-Star reviews and talking with my riding friends, one of which is a factory trained motorcycle mechanic, I concluded that high speed handlebar resonance is simply a function of riding a V-twin.

I am 5'5" short, so riding position probably contributes to my discomfort as I tend to lean forward putting weight on my hands and wrists. Changing my riding position may help alleviate some of my problem. I have also ordered a pair of Qwi gel gloves, handlebar weights, and Throttle Boss' to see if any of that works.

I will add to this post after applying these fixes to report on what might help/ not help.

PS: The ride I was on was with the Patriot Guards to escort a fallen hero from the Birmingham Airport to his hometown for burial. Sixty bikes escorted this young man from the airport and over 200+ bikes participated in the funeral procession yesterday.

This problem is probably worsened by the uneven main jets, one cylinder makes more power than the other. There is an article link off the SloanService page them talks about it and when putting pod air cleaners on the consensus is to have equal jets to smooth out the vibes.
