TroubleshootingleL;k lek/kkuAlthough YMIS Motorcycle receive
a rigid inspection before shipment
from the factory, trouble may occur
during operation. Any problem in
the fuel, compression, or ignition
systems can cause poor starting
and loss of power. The
troubleshooting chart describes a
quick, easy procedure for making
checks. If your Motorcycle requires
any repair, bring it to a YMIS dealer.
The skilled technicians at a YMIS
dealership have the tools,
experience, and know-how to
properly service your Motorcycle.
Use only genuine YMIS parts on
your Motorcycle. Imitation parts
may look like YMIS parts, but they
are often inferior. Consequently,
they have a shorter service life
and can lead to expensive repair
bills.;|fi okbZñ,eñvkbZñ,lñ eksVjlkbfdy
