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.

Intake Manifold: 1. Install MAP sensor in Mikuni manifold (Twin Cam only). 2. Attach the Mikuni manifold to the engine. Align the manifold before tightening the bolts. The flange surface of the Mikuni manifold should be parallel with the front of the engine’s cam cover. Use a level or angle meter to check this. Tighten the manifold bolts. 3. Attach the rubber flange to the Mikuni manifold with the furnished 5/16″x3/4″ bolts and washers. Choke Cables: Mikuni & Harley-Davidson Route the cable with largest radius bends possible. Check the cable for free-play after installation. If there is no free-play, the engine may run rich and deliver poor performance or low fuel mileage. Harley Cable (Twin Cam Kits: 42-19, 45-4) : 1. Remove the Harley choke cable from the stock carb. 2. Remove the spring and plunger from the cable. 3. Remove the spring and plunger from the Mikuni. 5. Install the Mikuni spring and plunger onto the Harley choke cable. Change nothing else; be sure to use the Harley plastic nut, not the Mikuni nut (See Figure 1). Total Kit Installation Instructions The HSR series carburetors are precise yet durable instruments; however, like any other piece of fine equipment, they require correct installation and reasonable care to assure optimum performance and long life. Extra time spent during installation will pay off in both short and long term performance and reliability. This Mikuni HSR carburetor kit is designed to be a bolt-on application, and as such, is set-up and jetted properly for most applications. However, since Harley-Davidson motors are often highly modified, alternate tuning settings may be required. The Mikuni Tuning Manual helps make jetting alterations and adjustments an easy matter. NOTE: Carburetor Kits not designated as C.A.R.B. exempt, are not legal for motor vehicles operated on public highways in the state of California, or in any other states and countries where similar laws apply. WARNING NOTE: NOTE: WARNING CAUTION NOTE: NOTE: TK-2 6. Install the new assembly into the Mikuni carburetor. Be careful to only gently tighten the plastic nut. 7. Loosen the knurled plastic friction nut behind the choke knob and check for free-play (see Figure 2). Figure 1: Harley nut with Mikuni spring & plunger Figure 2: Choke cable adjustments Mikuni Cable (Evo Kits: 42-8, 45-2 & 45-3) : 1. Remove nut, spring and plunger from the Mikuni. 2. Install the nut, spring and plunger onto the cable. 3. Install the assembly into the Mikuni HSR carburetor. Be careful to only gently tighten the plastic nut. 4. Check for free-play. Adjust the cable as necessary. An optional choke cable mounting bracket is included in the Evo kits for custom installations. Carburetor Installation: 1. Insert the carb fully into the rubber flange, align with engine and tighten the clamp. 2. Slip the fuel hose onto the carburetor’s fuel fitting and secure with the enclosed hose clamp. NOTE: Some Twin Cam installations may require removal of a small amount of fin material from the cylinders to clear the float bowl. Throttle Cables The HSR carburetor uses stock 1990 and later Harley- Davidson cables. However, if your Harley is fitted with some other carburetor, you may need to purchase a set of cables. See your dealer for the correct cable set. 1. Route the throttle cables with large radius curves and so they do not interfere with other components. 2. Screw the cable adjusters together to make them as short as possible. 3. Connect the “close” cable first (see Figure 3). 4. Install the “open” cable next (see Figure 3). 5. Adjust the opening cable until the slide can be opened fully. Snug the adjuster lock nut. 6. Turn the handlebar to the right and adjust the throttle free-play with the closing cable adjuster to approximately 1/8″ (see Figure 4)
