CAUTION:
Cobra recommends that you tell your child to take it easy the first couple of minutes
in practice until the engine comes up to full operating temperature.
Maintenance
It is important that you adhere to this maintenance schedule so as to promote the
longevity of your Cobra Motorcycle.
Tips
1. Cobra lubricants:
a. Use only high quality transmission oil designed specifically for two-
stroke racing engines.
b. Motul 800 2T Off Road oil is the recommended premix oil because:
• Its Ester base leaves a film on all parts at all times. No metal to
metal startups or corrosion potential.
• Exception film strength over petroleum based oils or synthetic
blends.
• Easily atomizes and burns completely.
• Does not fall out of suspension from premix in cold weather.
• Produces virtually no coking deposits, leaving pistons, rings and
heads extremely clean with minimal pipe ‘spooge’.
2. Fill your transmission only with the recommended amount of oil. Overfilling may
lead to premature seal failure.
3. The cylinder base gasket has been ‘fitted’ for your engine. See the service
section of this manual for instructions how to properly size a base gasket
during an engine rebuild.
4. Evaluate the bikes jetting only after it has been warmed up to race
temperatures.
5. A properly maintained machine is safer, faster, and more fun to ride.
6. New chains will stretch on first use. Never install a new chain prior to a race.
Always ‘break’ them in during practice.
7. Your Cobra Motorcycle has a 10 digit VIN (Vehicle Identification Number). The
first two digits indicate the model and the seventh indicates the model year
(MY).
a. Example, CXxxxx7xxx is a 2007 MY CX65.
Schedule
• Between each ride
o Check the air filter (clean and re-oil as necessary).
o Insure the smooth operation of the throttle cable (throttle soundly ‘clacks’
shut).
o Check for frayed strands of the throttle cable inside the throttle housing
and replace if necessary.
o Check for adequate tire pressures and adjust if necessary.
o Check all nuts and bolts for proper torque and re-torque if necessary.
o Spray all moving parts with WD40 or other water displacing oil.
o Check drive chain for
