The majority of HSR42/45 installations use the Harley cable. Installation is simple when the installation instructions are followed, step by step. Those steps are: • Remove the stock Harley choke cable assembly. • Remove the spring and plunger from the stock cable. • Remove the Mikuni “Starter Nut” from the HSR. • Remove the Mikuni spring and plunger from the HSR. • Install the Mikuni spring and plunger on the Harley choke cable. • Install the Harley choke cable with the fitted Mikuni spring and plunger into the HSR carburetor. • DO NOT use the Mikuni Starter Nut; discard it. • DO NOT use the Harley spring or plunger; discard them. Note: If you do not have installation instructions, you may download them from the www.mikuni.com website in the “manuals” section. If the Mikuni Starter Nut is fitted to the Harley cable, the choke plunger is held off its seat and the choke is open all the time. If the Harley spring and plunger are used, the plunger does not seal and the choke is open all the time. The result, in both cases, is very poor fuel mileage (30 mpg or less). Another possible cause of poor mileage, rough idle and fouled spark plugs is incorrect cable routing. The stock Harley choke cable is very stiff and may not be fully seated in the metal elbow at the carburetor end of its run. This condition is easily corrected. On occasion, one of these errors may have been made by someone else at another location. The unfortunate mechanic who inherits the task of correcting the rich condition, poor idle and poor fuel mileage may have no clue as to the mismatch of parts. For this reason, we include the photos and text to help you discover if your installation is correct.

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.

INSTALLATION : The spacer behind the front pulley should be removed prior to installing the belt drive. This spacer may or may not be required to correctly align the pulleys. If a spacer is needed for alignment, various sizes are available from your local Primo Belt Drives dealer (part number PX-1 =package of 6 various sizes). With all supporting components installed, install front pulley, lubricate and reinstall the clutch hub. Loop the belt around the front and rear pulleys, and gently push into place. Use the washer and nut supplied with the kit on the front motor shaft, (always use an impact wrench on splined shaft motors) tighten to 80-100 foot pounds of torque. After installing and adjusting clutch, track the belt by turning the pulleys. If needed us a straight edge between the front and rear pulleys to check alignment. Improper alignment of the pulleys will result in reduced belt life. Spacing the motor pulley outward will cause the belt to track towards the outer primary cover. If spaced too far out the belt will rub on the inside of the clutch shell. ENCLOSED INSTALLATIONS: The same disassembly is required, with the exception of the clutch hub and inner primary. We recommend using our PC-1000-Acomplete clutch assembly. Loop the belt around both pulleys to insure that you have the proper belt for your pulleys, then gently push the unit into place. Use the washer and nut supplied with the kit on the motor shaft. Torque the motor nut to 80-100 foot pounds . Adjust the clutch & check belt / pulley alignment. Before installing the primary cover be sure that everything inside clears both the outer and inner covers. In some cases a small amount of metal may need to be removed from one or more of the bosses on the inner or outer primary covers

Disconnect the engine breather hose from the bottom of the air box 5. Set the air-box to the side 6. Disconnect the plug going to the stock carburetor, this is the electronic choke. Wrap the end left on the vehicle with electrical tape. 7. Cut the fuel line just above the fitting on the passenger side of the carb 8. Remove the side cover off the drivers side of the carb where the throttle cable goes in, see fig. #1 9. Pull the throttle cable out and then remove the throttle cable end from the throttle plate See Fig. #2 10. Loosen the clamp on the rear of the carb holding the carb on 11. Pull the carb out of the intake boot 12. Set OE carb to the side. 13. Push the new Carb into the intake boot making sure the carb is perfectly vertical and then tighten the clamp back up. The new carb is slightly larger than the stock one so some additional pressure will be needed to get it in. 14. Route all the breather lines connected to the carb down under the carb. 15. Connect the throttle cable onto the new carb but putting the cable end in the bottom hole of the throttle plate on the passenger side of the carb allowing the cable to ride in the slot in the plate and then turn the throttle plate clock wise allowing the threaded end of the cable to fit into the lower round hole of the throttle cable connection plate. See Fig. #3 16. Make sure you have a nut on each side of the plate turn the nut on the outside of the plate to take up the slack in the throttle cable then tighten the nut on the inside of the plate. See Fig. #3 17. Push the fuel line onto the fuel inlet on the passenger side of the carb and install the supplied clamp to hold it on. The fuel line will be a little hard to push on. 18. DO NOT ATTEMPT TO INSTALL THE CHOKE CABLE PARTS SUPPLIED IN THE KIT UNTIL AFTER THE CHOKE CABLE ITSELF IS INSTALLED AND READY TO SCREW INTO THE CARBUETOR. 19. To install the supplied choke cable, drill a 3/8″ hole in the dash on the left side of the steering wheel in a location convenient to your left hand. 20. Remove the plastic nut from the bottom of the choke handle on the choke cable. 21. Push the choke cable thru the hole you drilled and then slide the nut over the cable to the inside of the dash and reinstall back on the back of the choke mechanism. Some dash screws maybe needed to be removed to accomplish this

Choke Dell’Orto carburetor PHVA 14 DS (50SXJunior) Choke lever [1] is mounted to the right side of the carburetor. If you move the choke lever up to the stop, a hole is opened in the carburetor through which the engine can draw in additional fuel. This results in a “rich” fuel-air mixture required for a cold start. Moving the choke lever back closes the hole in the carburetor again. Choke Dell’Orto carburetor PHBG 19 BS (50 SX) Choke control knob [2] is mounted to the left side of the carburetor. If you pull the choke control knob up to the stop and turn it 90º, a hole is opened in the carburetor through which the engine can draw additional fuel. This results in a “rich” fuel-air mixture required for a cold start. Turning back the choke control knob returns the knob to the starting position and closes the hole in the carburetor again. Kickstarter The kickstarter is mounted on the right side of the engine. Its upper part can be swivelled. Foot brake lever The foot brake lever is located in front of the right footrest. The basic position can be adjusted to the seating position (see maintenance work). Side stand (50 SXJunior) Use your foot to swing the side stand forwards to the stop.
