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.

the Akrapovic Racing and Evolution complete exhaust systems are the flagships of our product lines. They are designed for competition-oriented MX riders who demand maximum performance from their exhaust systems. With their production quality, engine performance improvements and modern Hexagonal muffler design they satisfy the requirements of all riders. The systems are designed for two markets; in the US they are available with an approved spark arrester, and for the EU and other non-US markets they come with a noise damper. New for 2008 is additional chamber that helps to reduce noise emission and provides better power and torque at low rpm range. PERFORMANCE Measurements of the Akrapovic EVOLUTION system on the KAWASAKI KX 250 F (with muffler insert): Power & Torque: The Akrapovic Evolution and Racing systems deliver a performance increase throughout nearly the entire rpm range. It is most pronounced in the bottom and the top of the range. The systems deliver increased torque similar to the power increase. Max. increased power of 0.7 HP was measured at 12260 rpm, while max. power of 34.6 HP was measured at 11400 rpm. CONFIGURATION Akrapovic Racing and Evolution systems are of a recognised Hexagonal off-road form. They differ only in terms of the material of the pipe: we use stainless steel for Racing and titanium for Evolution. The header tube is conical, made from stainless steel (Racing) or titanium (Evolution) with additional chamber. It is jointed with a conical SS/titanium link pipe by a sleeve joint, which is secured with a silicon-shielded spring. The link pipe is welded to the muffler. The inlet cap, due to the method of connection with the link pipe, is made from stainless steel (Racing) or titanium (Evolution), same for the internal perforation. The outlet cap is made of carbon-fiber for evolution and composite polymer for Racing system. The outer sleeve of the muffler is available either made from titanium or carbon fiber. The system is attached to the motorcycle with the Akrapovic carbon fiber clamp. The Akrapovic carbon fiber heat shield is also intended for this system. The system comes with a built-in noise damper for the European and other markets, and an approved spark arrester for the American market, which is marked with a laser engraving

1. Wash motorcycle, taking care to remove sand and other abrasive debris from engine and area of frame around engine. Remove battery, gas tanks, and all parts required to access original rocker covers. Remove top and center sections of rocker housings. Refer to authorized Harley-Davidson®Service Manual as necessary. Sparks from motorcycle electrical system can ignite gasoline fumes. To prevent sparks as well as prevent electric starter from becoming engaged inadvertently and causing personal injury, disconnect battery and remove from motorcycle before proceeding. Gasoline is toxic if fumes are inhaled, extremely flammable, and explosive under certain conditions. Do not smoke around gasoline, and perform installation in a well ventilated area away from sparks and open flame. 2. Remove pushrod cover retainer clips for front cylinder and collapse covers. Remove sparkplugs and rotate engine to place pushrods at lowest point on cam with front piston at TDC on compression stroke. Referring to Harley-Davidson®Service Manual as necessary, remove rocker assemblies, pushrods and lower rocker cover from front cylinder head. NOTE: Observe correct location of pushrods. S&S pushrod kits have longest pushrod for front exhaust, next longest for rear exhaust, shortest for rear intake, and remaining one for front intake. Remove all traces of old rocker housing gaskets from cylinder head, taking care to contain debris. Debris such as gasket material can interfere with oil circulation resulting in engine damage not covered under warranty. 3. Inspect S&S rocker cover assemblies. Remove rough or sharp edges from plain (unchromed) assemblies. Clean all metal parts with solvent. Dry with compressed air and remove any solvent residue with clean, lint free cloth. 3 CAUTION WARNING WARNING CAUTION 4. Install umbrella valves in rocker cover bases. See Picture 1. Valves go in vent ports nearest intake manifold on both front and rear rocker cover bases.

ISSUES: Harley Davidson recommends both gear lube and motorcycle oils for their equipment and there are many different models with corresponding specific oil recommendations. The variety of recommendations can cause confusion and lack of confidence in making the correct AMSOIL lubricant recommendation. The following charts outline the proper sequence of product recommendations for the Harley Davidson products listed. DESCRIPTION & RECOMMENDATIONS: Harley Davidson manufactured 9 types of engines from 1929 to the current model year. Flathead (1929-1974), Knucklehead (1936-1947), Pan- head (1948-1965), Shovelhead (1966-1984), Evolution (Blockhead) 1340 (1984-1999), Twin Cam (2000 to current), V-Rod (Revolution) (2001 to current) Ironhead Sportsters (1957-1984) & Evolution Sport- sters 1985 to current. Harley Davidson recommends SAE 60 or SAE 50 engine oil for Flathead, Knucklehead, Panhead, and Shovelhead equipped bikes . AM- SOIL recommends AHR SAE 60 or MCV 20W-50 motorcycle engine oil for these vintage models. AMSOIL SVT or SVO should be used in transmissions found on these models. Shovelhead is the only model with a chain case that is lubricated via engine oil. AMSOIL recommends MCV 20W-50 motorcycle oil in all 3 holes (engine, transmission, and primary chain case) on Evolution 1340 and all Twin Cam engines. AMSOIL recommends SVT as a secondary oil for the transmission, and SVO as an option for older transmissions. New seals are recommended where excessive leaking is evident. Ironhead, Evolution Sportsters and V-Rod use one lubricant for both the engine and transmission and AMSOIL recommends MCV motorcycle oil for this common sump.
