FUEL Fuel tank capacity: 2.0 US gal (7.4 liter, 1.6 lmp gal) To open the fuel fill cap, pull the breather tube out of thesteering stem nut. Then turn the fuel fill cap ounterclockwise. • Use automobile gasoline with a pump octane number of 92 or higher. If “knocking” or “pinging” oc- curs, try a different brand of gasoline or a higher octane grade. • Gasoline is extremely flammable and is explosive under certain conditions. Perform this operation in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where gasoline is drained or stored and where the fuel tank is refueled. 1.OPERATING INSTRUCTIONS WARNING BASIC OPERATION Starting The Engine • Never run the engine in an enclosed area. The exhaust contains poisonous carbon monoxide gas thatcan cause loss of consciousness and lead to death. • Attempting to start the engine with the transmis- sion in gear and clutch engaged may result in in- jury or damage. NOTE: • This motorcycle can be kickstarted with the transmission in gear by disengaging the clutch before operating the kickstarter. Check the engine oil, transmission oil and coolant levels before starting the engine (page 21, 23, 24). Cold Engine Starting: 1. Turn the fuel valve ON. 2. Shift the transmission into neutral. 3. If the temperature is 35°C (95°F) or below, pull the choke knob fully out. 4. If the temperature is below 0°C (32°F), open the throttle two or three times. (The engine requires a richer mixture for starting in cold weather. When the throttle is so opened, the accelerator pump will feed extra fuel to the cylinder, thereby facilitating starting in cold weather.) 5. With the throttle closed, operate the kickstarter starting from the top of the kickstarter stroke, kick through to the bottom with a rapid, continuous motion. (Do not open the throttle, As the carburetor is equipped with an accelerator pump, excessive fuel will be charged into the engine, and the spark plug will be fouled if the throttle is opened and closed repeatedly. Excessive fuel in the engine makes kick starting difficult.) 6. About a minute after the engine starts, push the choke knob back all the way to fully OFF. If idling is unstable, open the throttle slightly. (1) FUEL FILL CAP (2) BREATHER TUBE WARNING (1) FUEL VALVE (2) CHOKE KNOB Warm Engine Starting: 1. Turn the fuel valve ON. 2. Shift the transmission into neutral. 3. Pull the hot start lever and kick-start the engine. (Do not open the throttle.) 4. As soon as the engine starts, release the hot start lever.

LCD DIPSTICK INSTALLATION 1. Remove the original equipment (OE) dipstick from the filler neck. 2. Non-threaded Dipsticks: Lightly oil the O-ring on the new LCD dipstick. Orient the dipstick so that the display window is horizontal and readable from left to right, with the Bar and Shield logo to the left (towards the rear of the motorcycle). Push the dipstick straight into the filler neck until it seats. 3. For threaded dipsticks: Lightly oil O-ring and screw into the transmission like OE dipstick. If the orientation of the display is unsatisfactory when fully seated, refer to Adjusting the Display Angle later in these instructions. NOTE To be sure of correct readings, the dipstick MUST seat firmly against the flange. LCD DIPSTICK USE AND CARE Removing the Dipstick The dipstick assembly must be removed from the filler neck to add oil or to service the internal battery. Displaying the Oil Temperature and Level See Figure 1. Press and release the rubber button on the front face to display the temperature of the oil in the oil tank in degrees Fahrenheit (°F), and the oil level. The display will automatically shut off after approximately ten seconds. Do not overfill oil tank. Doing so can result in oil carryover to the air cleaner leading to equipment damage and/or equipment malfunction. (00190a) NOTES Oil level cannot be accurately measured: • on a cold engine • with the motorcycle upright • with the engine running NOTE Oil level on 2000 through 2004 Softail models with the original dipstick is checked with the motorcycle standing upright (not leaning on the jiffy stand). THIS IS NOT THE CASE with the LCD oil temperature/level dipstick. For all 2000 and later Softail models, oil level inspection must be done with the motorcycle LEANING ON the jiffy stand, on level ground. For pre-ride oil level inspection: With the motorcycle on level ground, RESTING ON the jiffy stand : •The oil level should be as indicated in Figure 1, display 4 through 8 (bars showing oil level, and “COLD OIL” message followed by flashing oil temperature) when the engine is cold. DO NOT ADD OIL to bring the level to the FULL mark on the dipstick of a COLD engine. •If the oil level indicates as in display 9 (animated level bars, followed by an “888 NO SENSOR” code), the wires inside the dipstick may be disconnected or damaged. Refer to Replacing the Battery later in these instructions to separate the dipstick upper and lower assemblies. If the small plug next to the battery has become dislodged from the receptacle, plug it in. If a visible wire is damaged, a repair can be attempted. If no damage is visible, the dipstick is damaged internally and should be replaced. For oil level inspection at operating temperature: Ride the motorcycle until the engine is at normal operating temperature. Idle for 1-2 minutes with the motorcycle on level ground, RESTING ON the jiffy stand (except Softails) , turn the engine OFF.

Clean the air filter Pull off the right-hand side panel and remove the two nuts which secure the air filter cover. Withdraw the cover, checking that the sealing gasket is in good condition, pull out the retaining spring and withdraw the element assembly. Peel off the inner and outer foam sleeves. Wash all components in white spirit (Stoddard solvent) or in warm water and detergent and dry them thoroughly. Soak the foam sleeves in the specified oil, then squeeze them gently (do not wring them out or they will be damaged) to expel all surplus oil. Refit the sleeves to the element frame. On reassembly ensure that all components are correctly fitted so that unfiltered air cannot bypass the element. 2 Check the spark plug Remove the spark plug cap, unscrew the plug and check its condition, comparing it with the photographs on page 65. If it is badly worn or fouled it must be renewed. If it is fit for further service check the gap and reset it if necessary, as described in Chapter 3.8. 3 Check the valve clearances It is important that the correct valve clearance is maintained. A small amount of free play is designed into the valve train to allow for expansion of the various components. If the setting deviates greatly from that specified, a marked drop in performance will be evident. In the case of the clearance becoming too great, it will be found that valve operation will be noisy, and performance will drop off as a result of the valves not opening fully. If on the other hand, the clearance is too small the valves may not close completely. This will not only cause loss of compression, but will also cause the valves to burn out very quickly. In extreme cases, a valve head may strike the piston crown, causing extensive damage to the engine. The clearances should be checked and adjusted with a cold engine. Place the machine on its centre stand and remove the rocker cover, taking care not to damage the 0 ring. Remove the gearchange pedal and the left-hand outer cover to expose the generator rotor. Remove plug and allow old oil to drain Remove the spark plug, then slowly rotate the engine anticlockwise by way of the generator rotor, watching the inlet valve. When it has opened and closed again (sunk down and risen up to its original position), rotate the engine further until the T mark on the rotor periphery aligns exactly with the raised index mark which is positioned between 12 and 1 o’clock (from the crankshaft) on the generator stator. The engine will then be in the correct position for checking the valve clearances, namely at Top Dead Centre (TDC) on the compression stroke; check that there is free play at both rockers. Using a 0.08 mm (0.003 in) feeler gauge, check the clearance between the top of each valve stem and its corresponding rocker. The feeler gauge must be a light sliding fit, with the rocker and valve stem just nipping it. If necessary, slacken the locknut, and turn the small square-headed adjuster to obtain the correct setting. Tighten the locknut, holding the adjuster at the same time to prevent it from moving. Finally, recheck the setting and then repeat the procedure on the other rocker. 4 Check the contact breaker points and ignition timing Note: since the generator stator plate is located by its countersunk retaining screws, the ignition timing can only be altered by opening or closing the contact breaker gap; therefore both operations are described as one. The full procedure is given here for ease of reference, but if the points are found to be in good condition and if the gap has not altered or is within the tolerance, then the ignition timing will be sufficiently accurate and there will be no need to carry out the full check. First remove the gearchange pedal, the left-hand outer cover, the spark plug and the left-hand side panel

motorcycle can be kickstarted with the transmission in gear by disengaging the clutch before operating the kickstarter. Check the engine oil, transmission oil and coolant levels before starting the engine (page 21, 23, 24). Cold Engine Starting: 1. Turn the fuel valve ON. 2. Shift the transmission into neutral. 3. If the temperature is 35°C (95°F) or below, pull the choke knob fully out. 4. If the temperature is below 0°C (32°F), open the throttle two or three times. (The engine requires a richer mixture for starting in cold weather. When the throttle is so opened, the accelerator pump will feed extra fuel to the cylinder, thereby facilitating starting in cold weather.) 5.

cold Engine and Drivetrain Procedures Check Alternator Belt Tools Parts T-handle hex – 4mm none Note: In most cases the alternator belt does not need to be checked any more. Early models should have the pulley and belt upgrade that came out a few years ago. Current recommendations are that the belt is installed and adjusted, then not disturbed until 36K when replacement is specified. 1. Remove the four bolts holding the black plastic alternator belt cover at the front of the engine, 4mm T-handle hex. 2. Remove the cover by sliding it straight down. 3. Check the belt for cracks or shredding. 4. Check the belt tension, quite tight, ~1/4″ deflection when you press on the center. Note: Paul Glaves suggests that proper belt tension is when you can twist the belt ~90 degrees, midway between the pulleys. If you can twist it more than 90 degrees, it is too loose. If you cannot twist it 90 degrees, then it is too tight. 5. Leave the cover off for the valve adjustment procedure on the next page. Change Alternator Belt Tools Parts T-handle hex – 4mm alternator belt socket – 13mm ratchet wrench – 13mm torque wrench 1. Remove the four bolts holding the black plastic alternator belt cover at the front of the engine, 4mm T-handle hex. 2. Remove the cover by sliding it straight down. 3. Loosen the 2 nuts and 1 bolt, 13mm, that hold the alternator – one is on top and one is on each side, thus allowing the alternator to pivot down. 4. Remove the old belt. (Some bikes have a pipe that traps the belt – loosen it enough to get the old belt out and the new belt in) 5. Install the new belt being sure it is properly seated. 6. BMW calls for a tensioning torque of 5.9 ft.lb. (8 Nm) on the adjuster bolt on the left side of the bike. You have to get at this bolt from the alternator side and you may have to lift the tank. Alternatively, you can pry the alternator up with a large screwdriver to tension the belt. 7. Once the belt is under proper tension, tighten the 2 nuts and 1 bolt, 13mm, to 15 ft.lb. (20 Nm). 8. Check the belt for proper tension (see above) and proper seating alignment

Starting Procedure Before starting the machine inspect the following: • Fill the 2-stroke injector oil reservoir with Cobra’s specially formulated Cobra Venom 2-cycle Race Oil . • Insure that the fuel tank contains an adequate volume of fuel to complete the distance required. ( Sunoco MO2X or 93 octane pump gas). • 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 do not have improper wear. • Inspect the frame for; o Cracks in the metal. o Cracking paint which might indicate overly stressed material. • Verify that the handlebars are tight. • Check the throttle for; o Smooth operation and sound closing. o Frayed strands of the cable inside the throttle housing. • Check for loose bolts and nuts, and re-torque as necessary. • Verify that the air filter is clean and properly saturated with 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. 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. On the carburetor, flip the black choke knob upward from the right side of the bike. 3. Kick start the engine by kicking the lever forward. 4. Rev the engine in short spurts, turning the throttle no more than 1/4 open until the engine will run without the choke. 5. Verify a functional engine shut-off switch by shutting off the engine. 6. Restart the engine and proceed with riding when the engine is sufficiently warm (i.e. the side of the cylinder is warm to touch). CAUTION: Never rev an engine full throttle when it’s cold or slightly warmed up. 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. Make sure your engine is properly warmed up before racing.
