Special tools are designed for remove and
install of components without damaging the
parts being worked on. Using wrong tools

When servicing this motorcycle, use only
metric tools. Metric bolts, nuts, and screws
are not interchangeable with the English
system, using wrong tools and fasteners may
damage this vehicle.
Clean the outside of the parts or the cover
before removing it from the motorcycle.

Rubber parts may become deteriorated when

oil. Check these parts before installation to
make sure that they are in good condition,
replace if necessary.
When loosening a component which has
different sized fasteners, operate with a
diagonal pattern and work from inside out.
Loosen the small fasteners first. If the bigger

receive too much stress.
Store complex components such as
transmission parts in the proper assemble
order and tie them together with a wire for
ease of installation later.
Note the reassemble position of the important
components before disassembling them to
ensure they will be reassembled in correct
dimensions (depth, distance or position).
