Maintenance; Tips - Cobra 2007 King 50 Service Manual

CAUTION:
Never rev an engine full throttle when it's cold or slightly warmed up. Also, for
best clutch performance, warm up the bike before taking off.
This is a high performance race motorcycle. Too much application of throttle will
likely land your little racer on his or her arse. Fenders can be replaced but
bruised egos and other body parts take longer.
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.
CAUTION:
Make sure your riders' foot is not resting on the foot brake while they are riding
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. Cobra Clutch Milk has been specifically formulated to meet the
stringent temperature, frictional, and load requirements unique to
the high engine speeds and centrifugal clutch of the Cobra 50cc
motorcycles.
b. Cobra Two Cycle Oil exceeds the JASO FD & ISO-L-EGD
specifications, which are the worlds most stringent requirements on
lubrication, detergency, and smoke. Use only a 2-cycle oil that
meets these specifications.
2. Filling your transmission with more than 8.0 oz (235 cc) of lubricant may
help to transfer heat from the clutch. Filling with more than 12 oz (295 cc)
will degrade performance.
3. The cylinder base gasket has been 'fitted' for your engine. The code
number stamped into the engine cases will guide you to what thickness
base gasket is required during a common top end service. See the service
section of this manual to correspond a code number with a base gasket part
number.
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.
