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.

Checking the electric starter motor for wear -Check Bendix 1 for smooth operation and signs of wear. -Check the sprocket of the electric starter for wear and radial clearance. -Replace O-ring 2 of the electric starter. -Replace gasket 3 . -Check starter idler gear 4 for smooth operation and wear, check that the bearing bushings are seated firmly. Electric starter motor – checking for and adjusting play -Mount the electric starter and the starter idler gear. -Mount the tighten cover 5 . -Move starter idler gear 4 back and forth in the direction of rotation, the maximum play may not exceed half the width of a tooth. -If play is larger, cover 5 must be removed and as many shims 6 with a thickness of 0.10 mm as necessary must be added to eliminate all play. Then remove one shim again. -Check the play again; the maximum play may not exceed more than half of the width of a tooth. 1 2 3 4 5 4 5 6

Use a 10mm ratchet attachment to remove the battery from the vehicle. Negative terminal first, then positive. Be careful not to cause an arc between the two terminals as intense pain will result.
Remove the plastic plate that the battery sits in. 2. Using the 10mm attachment again, remove the 6 bolts that hold the passenger side front splash guard from underneath the front bumper. 3. From underneath the vehicle, locate the oil filter. Look above oil filter and you will see the starter. Locate the bottom 14 mm bolt that attaches the lower portion of the starter to the engine. The bolt drives from left to right. The starter is mounted toward the front of the vehicle and underneath the intake manifold. Still cant find it?
Follow the cable that leads from the positive battery terminal. It ends at the starter. Not sure you have the right bolt? Stick your 14mm attachment on it with your fingers and see if it fits on properly
