I adjusted the belt and centered the axle to the pin holes on the swing arm. Axle wasn't quited centered before the belt adjustment but the tire didnt rub. The right side was back about an 1/8 inch. I aligned the wheels as that measurement was off about a quarter inch short on the left side. Didnt help. The bike had been wrecked when i got it. Replaced down tubes, front tire and wheel, carb, tank and right controls

The belt tensioner gauge should be placed on the drive belt as close to its middle section as possible and pushed against the belt with a pressure of 10 pounds to see how far the belt deflects. You need to know the proper 10 lb pressure belt deflection for the particular year and model of bike. Once you know what the deflection should be if the belt is too tight loosen the axle cone nut and adjust the wheel forward to get the correct deflection and then tighten the cone nut to the correct torque for the model and year of the bike and retest the deflection to be sure it has remained the same throughout the cone nut tightening procedure. If the belt is too loose adjust the wheel more towards the rear of the bike and do as above for properly tightening the axle cone nut and recheck the deflection again as above. To maintain correct wheel alignment adjust each side of the wheel equally forward or backwards as the circumstances require. In case the alignment was not correct when you began OR to be certain that you adjusted each side equally measure the distance from the center of the swing arm attaching fasteners (or some other precise point on both sides of the swing arm - some swing arms have special measurement holes in the rear swing arm) to the middle of the axle. It should be the same measurement plus or minus 1/32nd of an inch maximum on each side. If it is not then you need to adjust one or both sides forward or backwards to get this measurement within the proper specs and then ensure that you have the correct belt deflection and if the belt deflection is then incorrect you need to go through the belt deflection adjustments procedures to get it within the correct specified 10 lb deflection amount while keeping the axle measurements equal within 1/32 inch from side to side.
I do not have the torque or deflection specs for a 1993 FXR at hand so if you do not have them you will need to get them somewhere else.
Hi anonymous, first you need to check rear wheel alignment in the swing arm either from the center of the swing arm pivot shaft to the center of the rear wheel axle bolt (most accurate method) measurement should exactly the same on both sides. Or you can use the axle adjuster marks stamped on the swing arm where the axle lives. next you need to get the rear wheel off the ground and rotate it in the direaction of forward movement and see where it tracks in the pully. If it tracks to one side and rubs against the pulley side walls then you can adjust the pulley location by adding or subtracting pully to hub spacers so it tracks in the middle or away from any wall. If it is mechanically impossible to achieve this desired outcome you may slightly adjust rear wheel to achieve desired results. If belt still squeeks you can try deglazing the inside of the pulley wall with scotch guard pad some simular mildly abrasive object and rub some dielectric grease on the side of the belt. All other remedies are less effective and only last for a day or two but you are surely welcome to try your own brew. Finally there is a question of proper belt tension, a belt to tight will squeek more than a loose one. For proper belt adjustment enjoy the video. Good luck
Raise rear tire off ground. Loosen chain adjusters, loosen and remove axle nut and remove axle. Remove chain from rear sprocket. Remove bolt from lower shock mounts. Loosen nut on swing arm and remove swing arm bolt.
Hi put your bike on the side stand get some blocks or something to put under the frame as far back under the frame tp lift the rear wheel off the ground spin your tire maybe the mechanic adjusted the rear wheel off center and its rubbing the fender, swing arm. or belt guard.

To adjust the rear belt, first loosen the rear axle nut. Then loosen the lock nuts on the adjusters on the rear of the swing arm. Measure the lengths of the adjuster bolts of each adjuster. You want to move the wheel to the rear to apply more tension to the belt while keeping these two bolts as near the same length as possible. This keeps the rear wheel in alignment in the swing arm.
Now move the rear wheel back slowly by turning the nuts on the adjuster bolts a couple of "flats" at a time until you get the proper tension on the rear belt. Once you get it there, retorque the rear axle nut to 50-60 foot pounds.
the belt should be adjusted to have about a 1/2" deflection when a ten pound pressure is applied in the center of the lower run of the belt with the rider on the bike.
The belt adjusting screws are on the ends of the swing arm arms if I'm not mistaken. To insure the rear wheel is aligned inside the swingarm, these two bolts must be adjusted to equal lengths.
Start by loosening the rear axle and the adjusters and moving the rear wheel forwards. Now, measure the bolts and set them to the same length. Slowly start to pull the rear wheel back by turning the nuts on the adjusters equal amounts on each bolt. Once you get the belt tension correct the bolts should be the same length.
Some swing arms have a "punch mark" on the outside of the swingarm about 6-8" in front of the axle. A Dyna Wide Glide has them. If your bike does not have exposed bolts that you can measure, look for these. Measure the distance from this "punch mark" to the center of the axle. If must be the same on both sides of the bike.
You don't need to download any information, just use your head. Taking the rear tire off is simple and putting it back on is simple with a bit of knowledge.
First loosen the axle nut. On the adjusters on either side of the axle, loosen each of them and allow the wheel slide towards the front. Now, start pulling out the axle. Depending on which way the axle was put in, different things will come out. Watch for various spacers. Make sure you mark the spacers and make a drawing of where they go and in what direction they go in. The will be one the belt side of the wheel. The brake bracket is on the other side. there are usually one short one on each side that goes into the wheel bearing seals as well. Once you have the axle out, work the belt off the rear pulley and get the wheel out from under the bike. You may have some belt guards that need to come off as well.
When you put the wheel back on, it's simply the opposite of taking it off. Now, you must adjust the rear wheel and belt tension. Measure the adjuster bolts one each side of the wheel. They must be as close to being the same as possible to ensure the wheel is straight in the swing arm. Adjust the belt so you have about a half inch up and down movement with ten pounds of upward force applied in the center of the lower run on the belt. If you don't get the belt tight enough, it'll usually make a "squeak" sound every time you shift gears.
In regards to the front wheel, there is little or no adjustment to align it to the frame assuming that the fork tubes and triple trees are not tweaked/bent or loose and that things are torqued to specks.
The unit in the bottom pic gets installed on the rear wheel, in other words the rear wheel is between the two plates in that pic. The dowel with the black sleeve goes through the spokes while the lower one goes beneath the tire to hold it in place.The yellow velcro strap holds the two halves tight to the wheel once installed. The brake pedal is applied to hold the wheel from rotating when it is in proper position.The two rods slide into the ends of those plates and extend forward to the front wheel to center the rear wheel using the adjusters on the rear wheel/axle.
You can also use a wire like a wire coat hanger to make a jig to measure to the center of the rear axle forward to the swing arm bolt center. Take a straightened out piece of hanger and put a small "L" on the end of the wire about 1 1/2 " that would go into the center/indentation in the swing arm bolt. Use a small "O" ring or the like as a slider on the wire and slide it to the center of the axle once the forward end is in place in the center of the swing arm. Measure both sides and adjust accordingly to get them even. This is done also keeping the belt tension in mind too. This system works for most but using the setup that I have, the measurement is much more fine/accurate in that you are extending the rods to the front wheel and turning the rear axle adjusters 1/2 turn will see a big difference when extended 8' or so to the front wheel. I think you can see where I'm going here.
Your best bet is to look in the factory manual, it describes the procedure pretty well.
