How do you know if a front wheel was blanced incorrectly? I just got a 21 front wheel a few weeks ago. When I ride it seems to wobble a little bit at 75 MPH. Its a very small wobble that I can see at the right end of the handle bar. Could the wheel blancing cause this to happen? Thanks, Ben

 

Put some Dyna Beads in it and call it a day!

 

Pull the wheel off.

Get a piece of dead straight steel bar or pipe (not rebar, something smooth) small enough in diameter to fit through the bearings on your front wheel.

Set the bar on two jackstands, tire on the bar in between.

Test: Spin the tire and wait for it to stop. Mark the top spot with chalk. Repeat this 4-5 times. If you end up marking nearly the same spot, that is the light spot on the tire. Apply a very small sticky weight with TAPE (temporary for now) and repeat the procedure until the tire is stopping at a different point every time.

Once you have the weight and location nailed down, affix it for real.

You are now balanced.

 

If it is not a balance problem, do a search in the forum and see what you can find on 21" wheel perforance problems. A while back there was talk of the 21" wheels not matching up well with the rear wheel.

 

I have some chrome wheel spacers coming tomorrow. Ill take the wheel off and have another shop check if it was blanced correctly. Hate it when stuff if not done right. Thanks Guys

 

could also be a tire, u can balance a brick ,doesnt mean its round.

 

I would get it checked, I continued riding mine with the 75 mph vibration and now I have a spot on the tire that is worn thru the wear bars. Dyna beads did not fix by the way.

 

I do remember the tire being hard for the guy to install. They also balanced the wheel without the rotors. Do you guys think that would cause the wheels to be off on the balance?

 

Usually a wheel off balance you would feel a vibration of a
up and down scenario..
Check your spokes Bro.. Wobble is often connected to loose spokes, run out or bad bearings.

 

The rotors are part of the rotating assembly and could be out of balance. Definitely balance the wheel & tire with the rotors on.
