PREVENTIVE MAINTENANCE
STORAGE
In the event your vehicle is not to be operated for a period in excess of 30 days and at the end of riding
season prepare for storage as follows:
WARNING
-
Do not drain fuel while engine is hot. Be sure to move
vehicle outside before draining fuel.
1. Drain fuel tank and remove all fuel remaining in the tank by using a suction device or by soaking up
the fuel with a clean rag or towel. Remove all fuel remaining in the carburetor by allowing engine
to run out of fuel. Do not perform any fuel removal procedure while smoking or near an open flame.
Dispose of any rags or towels properly.
2. Lubricate engine cylinder by removing the spark plug and pouring an ounce of lean lubricating oil
through the spark plug hole into the cylinder. Crank the engine slowly to spread oil and replace spark
plug.
3. Do not save or store gasoline over winter. Using old gasoline that has deteriorated from storage will
cause hard starting and affect engine performance.
4. When the vehicle is removed from storage reread the owner’s manual, perform any assembly
required, and perform a pre-ride inspection. See Pre-Ride Inspection section of this manual.
GENERAL
Just as your automobile needs professional, mechanical maintenance from time to time, so does this
vehicle. Replacement of the spark plug and ignition points is made necessary by normal use.
Professional air-cooled engine service is easily obtained. Check your phone book yellow pages under
“Engine Gasoline”.
