Check chain tension
Jack the motorcycle up on its frame so that the rear wheel no longer tou-
ches the ground.
Press the chain upward at the end of the chain sliding component. The
distance between the chain and the swing arm should be approx. 8 - 10 mm
(0.31 - 0.39 in). In the course of this procedure, the upper chain portion A
must be taut (see drawing). If necessary, correct the chain tension.
