Title: Rear wheel alignment              
Post by vtail on 12/10/07 at 19:01:53

Oke you asked for it, thou shall receive;
Take 2 pieces of rope or masking tape (in pics)of aprox 25ft and put tight on the ground (with rope use weights) about 2.5 to 3" apart like in this picture

Run bike forward, while sitting on it, till the end between the lines

Now check if rear wheel is centered.

This one below shows a bike that walks like a dog.

Do NOT rely on those marks on the swingarm. :) :)
Sorry about the picture quality due to compression :(

Now all I need is a room that is 25 feet long with a lot of clear space ::)

About how far off were the alignment marks to get that misalignment?

I like this idea.  I may try using a chalk-line instead though.

following a crack in the cement should be good enough.
Just set up on the tread pattern and measure the drift.

You can do this on the sidewalk or your driveway. I prefer string (rope) with the ends taped to the surface with duct tape. For this demo I used masking tape for visibility.
The swingarm has 6 marks. To get mine correct the notch on the adjuster is on one side is behind the 3rd (tall), the other side in front of the 3rd mark. That may not seem like a lot but any small adjustment there amplifies big on final alighnment ;)

Sure, but some folks have ashfalt or dirt and no sidewalks. So you can drive a nail in the ground as a tie-down. Kind of silly to travel to town to align your bike. ;D ;D

Perhaps you can use the white line on the road?  ;D

A pair of laser levelers would take care of you just about anywhere  ;)

Obviously, the farther you go, the more pronounced the error, but you don't need 25ft IF you have a keen eye.

Yep it does, but this is a matter of offset. ;) If you look close you'll see that there is also space on the right side of the belt. It does NOT rub the inside guard. On a lot of cars the cambelt does not ride in the middle of the pulley and those do not have guards since they are none adjustable and can not be out of alignment due to being in the same plane (due to machined and fixed alignment) Our race cars have toothed belt driven waterpumps witout guards and the belt does not ride exactly in the center ;D ;D

Now I understand why they were selling me this new bike (had 1 mile on it) sooooo cheap.

See...my "position" on the belt centering issue is actually neutral.

First, I don't believe that you can realistically make it ride in the center.

Second, I don't think it has a darn thing to do with belt squeaking.

Therefore, your belt looks just fine to me ;D

Actually I've run mine on a jack on the lift and watched it go from one side to the other on the rear pulley as you go from drive to coast with the engine running. I've replaced the drive cushions once in mine in a effort to minimize the squeak. I don't her it being more than a little hard of hearing, but others have commented and ask "what is wrong"? I just try to minimize it and motor on.  Max

By golly, I'm glad that someone finally agreed with me.  The on and off again engine torque is going to pull the pulley and cause the belt to shift from side to side continuously because the pulley is rubber cushioned.  Therefore a "static' adjustment to center the belt is a waste of time.

Just align the wheel and leave the belt looser to get rid of squeak.

Well that's what this topic was all about. Align the wheel and the belt might not be centered just like in the pictures :)
