I assume you want to know how to replace a final drive belt on a Sporty. First off, be glad you ain't working on a Big Twin. Sportster's are much easier than Big Twins to replace the belt on.
First, get the bike off the ground where you can remove the rear wheel. Then, remove the rear shock on the right side. Remove the bolts from the rear master cylinder and the large nut that holds the right foot peg on. Remove the front pulley cover.
Take the new belt and install it with the right leg of the swing arm through the belt. You may can work the belt over the front drive pulley. If not, use an air wrench to remove the pulley and install the belt. Retorque the pulley to 110-120 foot pounds. Remember the threads on this nut are left handed.
Reinstall the rear wheel and shock absorber. Adjust the belt to the proper tension. Then replace the front pulley cover and rear master cylinder.
Check the rear brakes for proper operation.
Good Luck
Steve
