the fuel, compression, or ignition systems can

procedure for making checks. If your vehicle
requires any repair, take it to a Yamaha deal-
er.

ship have the tools, experience, and know-

they are often inferior. Consequently, they
have a shorter service life and can lead to ex-
pensive repair bills.

smoke and make sure there are no open
flames or sparks in the area, including pilot
lights from water heaters or furnaces.Gasoline or gasoline
