Break-In Procedure
Your Cobra CX65 is a close-tolerance high performance machine and break-in time
is very important for maximum life and performance. The CX65 can be ridden hard
after the first ½ hour break-in time.
Cobra recommends Motul 800 T2 premix oil with high octane
pump gas mixed at 50:1 (50 ml oil to 1.3 gallon of gas, or 38ml oil to 1 gallon of gas).
Other brands of oil should be mixed at 32:1 for break-in.
CAUTION:
Failure to use proper fuel, oil, or fuel/oil mixture may result in premature engine wear
or damage to the machine.
Adhering to the following break-in schedule will result in long lasting high
performance machine.
• Start bike on stand
• First 5 minute period, operate the bike on the stand with a combination of idle
and high RPM operation. (avoid prolonged high RPM but spin the rear wheel
good at least once or twice per minute)
• Allow bike to cool
• Ride for 15 minutes maximum (avoid prolonged high RPM operation and avoid
abusing the clutch).
• Cool and inspect bike for loose fasteners.
• Check & retighten wheel spokes
• Next ½ hour of operation, avoid prolonged operation at Wide Open Throttle.
• After 1 hour of operation
o Check for loose bolts and nuts on the bike and retighten as necessary
(proper toque values are listed under Specifications).
o Clean the carburetor bowl.
o Change the transmission / clutch lubricant.
• After 8 hours of operation
o Change the fork oil.
o Have a Certified Cobra Mechanic change the shock oil.
• Your bike is now ready for the highest level of competition!
NOTE:
During break-in the bike will likely lose some engine coolant through the radiator
overflow hose. Losing up to 4 oz (120 ml, ½ cup) is normal. Proper coolant level will
cover the top of the radiator cores. Removing the radiator cap and looking inside is
the only way to check the coolant level.
Never open the radiator cap of a machine that has a hot or warm engine or one that
has recently been ridden. Burning and scalding could occur.
