How to change the handlebar position
The handlebar position can be readjusted by 22 mm. Thus, you can put the
handlebar in the position that is the most convenient for you. The upper triple
clamp [1] includes 2 bores arranged at a distance of 15 mm (0.6 in) from
one another. The bores at the handlebar support [2] are offset from the cen-
ter by 3.5 mm (0.13 in). Accordingly, you can mount the handlebar in
4 different positions.
For this purpose, remove screws [3] of the handlebar clamps and screws [4]
of the handlebar support. Position the handlebar support, and tighten screws
[4] to 40 Nm (30 ft.lbs). Mount the handlebar and handlebar clamps, and
tighten screws [3] to 20 Nm (15 ft.lbs). The gap between the handlebar sup-
port and the handlebar clamps should be the same size in the front and in
the rear.
The screws [4] must be secured with loctite 243.
Check chain tension
Jack the motorcycle up on its frame so that the rear wheel no longer touches
the ground.
Press the chain upward at the end of the chain sliding component. The dis-
tance 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.
If the chain tension is too great, parts within the secondary transmission
(chain, chain wheels and rear wheel bearings) will be subjected to unnec-
essary stress, resulting in premature wear and even chain breakage.
Too much slack in the chain, on the other hand, can result in the chain
jumping off the chain wheels. If this happens, the chain could also block
the rear wheel or damage the engine.
In either case the operator is likely to lose control of the motorcycle.
