1. Adjust Chain SlackChain Adjustment

Since you loosened both chain adjusters three turns, they should still allow for proper axle alignment. Follow your usual chain-adjustment routine and tighten each tensioner in equal increments until the proper amount of chain slack is reached. With the exception of eccentric adjusters, you can only move the axle away from the countershaft sprocket via the adjusters. So, don’t get carried away or you’ll have to start all over from scratch. Small adjustments of a quarter turn (or less if your chain is only slightly loose) are the safest bet. Measure the slack after every change. When the chain is within factory specifications (usually around 1.2-1.5 inches), tighten the axle nut to keep it from slipping. If you go too far and the chain becomes too tight, loosen the chain adjusters two full turns and use a rubber mallet or dead-blow hammer to knock the rear wheel forward against the adjusters and begin again.

When the chain has the proper amount of slack, torque the axle nut. Next, tighten each adjuster about one eighth of a turn against the axle. Hold the adjuster in position and set the lock nuts.
