DRIVE CHAIN
The service life of the drive chain is dependent
upon proper lubrication and adjustment.Poor
maintenance can cause premature wear or
damage to the drive chain and sprockets.
The drive chain should be checked and lubricated
as part of the Pre-ride Inspection. Under severe
usage, or when the motorcycle is ridden in
unusually dusty or muddy areas,more frequent
maintenance will be necessary.
Inspection:
1.Turn the engine off,place the motorcycle on
its side stand and shift the transmission into
neutral.
2.Check slack in the lower drive chain run
midway between the sprockets.
Drive chain slack should be adjusted to allow
the following vertical movement by hand:
25-35mm(1.0-1.4in)
3.Roll the motorcycle forward, stop, and then
check the drive chain slack. Repeat this
procedure several times.Drive chain slack should
remain constant.If the chain is slack only in
certain sections, some links are kinkied and
binding.Binding and kinking can frequently be
eliminated by lubrication.
NOTICE
Excessive chain slack may allow the drive chain
to damage the engine cases
