FINAL DRIVE
Maintenance of propeller shaft splines and final drive.
Remove the final drive from the swing arm and pull the final drive towards the rear of the bike.
When the drive shaft is free, coat the drive shaft splines with grease. At the same time, use a
grease gun to force grease into the drive shaft universal joint.
Typical final drive maintenance includes tightening the nuts which fasten the final drive to the
swinging fork arm. Failure to tighten the nuts may result in loose joints and the destruction of the
final drive cover. Change the final drive oil as determined by the service coupons. Undo the filler
and drain plugs and drain the used oil. Fill the casing with fresh 20w / 50 Castrol oil and flush the
final drive by turning the rear wheel several times. Drain the 20w / 50 Castrol oil and then refill the
final drive with the specified lubricant.
