Vibrating mirrors

Post by blueultra »



My side mirrors have begun vibrating violently at road speeds. (75-80 mph). I have checked tires and made sure they are balanced. Engine running smoothly and accelerates per normal. I have checked and tightened mirrors. Do not feel any excessive vibration in handlebars. Any idea's anyone?

Well, there are a lot of variables here. How many miles on you're bike, What brand tires, how are they balanced, If all the obvious is ruled out, and it is getting up into the higher mileage range, my guess would be U-joint on the drive shaft. Just my .02

All mirror vibrations I have known have been balancing or tyres, mine was rear wheel out of balance.
If at first you don't succeed, hide the evidence.

Bike has 74K. Dunlap elite 4's have about 4K on them. Traditional weight balance. There has been some vibration for some time, but has increased to point can hardly make out anything.

Well, you are about half way thru the tire life, and I personally never had any luck with Dunlop tires, so you could bite the bullet and get a new set of tires or at least the rear and I would throw out the wheel weights and use Dyna Beads for balancing. If that doesn't do the trick, I will stand by my previous thoughts and say it is a drive-line related issue such as the U-joint. I have an 05 Wing and I run Bridgestone tires with Dyna Beads and have never looked back. Rock solid ride at 85-90 MPH.

Each mirror has but one screw that holds it in place but did you check the three bolts that holds each mirror assembly in place for tightness?

You meed to eliminate wheel balance, it matters not the age and mileage of tyres, dont know about US but costs nothing in the UK to have it checked if you take the wheels in. You could have new tyres and winger could be right.
A good tyre place will tell you what speed the wheel will vibrate if out

Thanks....will next take to local Honda shop to check balance issue first and then proceed to check U-joint. Problem is deteriorating. Put about 200 miles on this weekend and vibration at 80 mph too extreme to make out anything in rear view mirror. Thanks all...will post results.
