I Premix gasoline and oil in a ratio of   20:1 Prepare the fuel mixture in a clean container, and shake until thoroughly mixed before Flling the fuel tank. i Too much oil will muse excessive smoking and spark plug fouling. Too little oil will cause engine damage or premature wear. Mix fuel in a ratio of 20 parts gasoline to 1 part oil. I Vegetable oils separate from gasoline more easily than mineral oils, especially in cold weather. It is advisable to use mineral oil when ambient temperatures of below 0°C (32°F) are expected. I If the gasoline-oil mixture is left standing in a container for a long period of time, lubricity will deteriorate. Use the mixture within 24 hours. I Once an oil container is opened, the oil must be used within one month, since oxidation may occur. Do not mix vegetable and mineral oils. Gasoline is flammable and explosive under certain conditions. Always stop the engine and do not smoke or allow open flames or sparks near the motorcycle when refueling

(Part # MCMUOL02) 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 with throttle blipping. • Cool and inspect bike for loose fasteners. • 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. 8 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. CAUTION: It is important that the radiator cap is installed correctly and completely otherwise engine damage could occur. Starting Procedure Before starting the machine inspect the following: • Check for proper tire pressure in both tires. • Observe the chain tension and adjust if necessary. • Observe the coolant level and fill if necessary. • Verify that the chain rollers and sliders do not have improper wear. • Verify that the handlebars are tight. • Check the throttle for smooth operation and that it ‘clacks’ shut properly. • Check for loose bolts and nuts, and re-torque as necessary. • Verify that the air filter is clean and properly saturated with oil. • Insure that the fuel tank contains an adequate volume of fuel / oil mixture to complete the distance required. (High octane pump gas with Cobra’s specially formulated Cobra Venom 2-cycle Race Oil ) • Turn the fuel on by rotating the fuel petcock knob to the vertically downward position (reserve position is horizontally forward

The CX50 SR can be ridden hard after the first ½ hour break-in time but it is recommended that no adjustments are made to the carburetion or suspension until the full 8 hours of bike break-in has elapsed. Also, after the engine, transmission, and drive train have been broken-in for the full 8 hours, the bike will be faster! Use a fuel / oil mixture of 32:1 for the full 8 hour break-in period. Be sure to use high-octane pump gas, with Cobra’s specially formulated Cobra Venom 2-cycle Race Oil .

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. CAUTION: It is important that the radiator cap is installed correctly and completely otherwise engine damage could occur. Starting Procedure Before starting the machine inspect the following: • Check for proper tire pressure in both tires. • Observe the chain tension and adjust if necessary. • Observe the coolant level and fill if necessary. • Verify that the chain rollers and sliders do not have improper wear. • Verify that the handlebars are tight. • Check the throttle for smooth operation and that it ‘clacks’ shut properly. • Check for loose bolts and nuts, and re-torque as necessary. • Verify that the air filter is clean and properly saturated with oil. • Insure that the fuel tank contains an adequate volume of fuel / oil mixture to complete the distance required. (High octane pump gas with Cobra’s specially formulated Cobra Venom 2-cycle Race Oil ) • Turn the fuel on by rotating the fuel petcock knob to the vertically downward position (reserve position is horizontally forward) CAUTION: For best results from your Cobra Motorcycle use only the recommended fuels. Testing has shown that most ‘race’ fuels actually degrade performance. Always wear a helmet and other protective riding gear. When your pre-ride inspection is complete the bike may be started. For a cold engine follow this procedure. 1. Place the motorcycle on a stand of sufficient strength that positions the motorcycle in a level upright position with the rear wheel off the ground. 2. Pull up the choke knob and turn it to lock it. 3. Kick start the engine. 4. Rev the engine in short spurts, turning the throttle no more than 1/4 open until the engine will run without the choke.
