Tuning the HSR42/ 45 Carburetor

your Mikuni HSR is fitted with the tuning parts we found to work with the great majority of engine performance modifications. However, the large number of differing exhaust systems and cams available makes it impossible to accommodate all possible combinations with one carburetor set-up. Your HSR will almost certainly run correctly on your engine without exchanging any parts. But, if it doesn’t, you may alter its tuning to suit your engine’s needs by following this guide. Some exhaust system designs strongly interfere with carburetor tuning. For instance, it is very difficult to get smooth and responsive carburetion through the entire rpm range with straight pipes and completely open exhausts. In addition, very small volume, small diameter mufflers are often ‘seen’ by the engine as straight pipes and present the same tuning difficulties. Very long duration cams often cause relatively poor running below about 3,000 rpm, depending upon the individual cam’s intake valve closing point. Such cams cause reverse airflow out the mouth of the carburetor (often called “reversion” or “standoff”) that can be mistaken for a carburetor tuning problem. Harley-Davidson Screamin’ Eagle performance parts are proven and predictable. If you have any doubts about a particular exhaust system, air cleaner or ignition, you may substitute the Harley Screamin’ Eagle parts as a “reality check.” When re-tuning is required, it usually involves small alterations to the idle and/or main system. The following pages supply enough information to make such alterations relatively simple. Please note that there is no point in attempting to tune any carburetor unless the engine is sound and in a good state of tune. If you have any doubts about the general condition of your engine, have it checked by your dealer or an experienced mechanic before attempting to fine-tune your Mikuni.

The shock has an adjustable rebound and standard Hi/low compression. The optional independent hi/ low compression adjuster has a low speed brass screw and a seperate blue high speed hex. The rebound adjuster is at the bottom of the shock. The standard setting is 8 clicks out (counter clockwise) from full hard. To increase rebound damping turn the adjuster in (clockwise), this will slow the extension of the shock. To decrease rebound damping turn the adjuster out (counter clockwise) this will quicken the extension of the shock. The standard compression adjuster has a the slotted brass screw on the reservoir. The standard setting is 12 clicks out low/hi speed brass screw(counter clockwise) and 1.75 turns out on the blue hex high speed adjuster from full hard. To increase compression damping turn the adjuster in (clockwise) – this will stiffen the compression of the shock. The low speed compression adjuster will soften small bumps and improve traction. The optional high speed adjuster will firm up the damping for big hits with no loss in small bump compliance, firmer settings will improve pedaling as well, lighter settings will smooth out square edge hits. Spring preload can also be changed to tune the shock to the weight of the rider. The shock spring preload can be varied by tightening or loosening the preload collars. The standard preload is 1.5 turns, (min 1 turn / max 3 turns). The rider sag must be adjusted to 1/3 of the total stroke with the rider sitting on the bike. This is the difference from fully extended position to the rider sitting. The ride height can be raised or lowered ± 5 mm to quicken or slow steering within the range of preload settings

The Repair Manual provides information on setup, tune-ups, servicing, diagnosing problems, removing and installing components (otherwise referred to as “assembly units”), overhauling components, adjusting repaired components, and testing the repaired motorcycle. The increasing competition in the motorcycle market requires, more than ever, careful attending to the customer in order to assure the owner satisfaction with one’s motorcycle and to maintain customer confidence in the dealer and factory. It is important to repair the client’s vehicles correctly in a well organized and clean repair shop equipped with all necessary tools and parts. In such an environment, and having been trained at the technical training course, a repair technician will prove to be competent and efficient. Repairs on the engine and transmission especially, should be carried out in dust-free places. During breaks, disassembled transmissions and openings leading to the inner engine parts or lubrication holes should be protected from dust by clean rags. Valves, valve springs, spring retainers, rockers, pushrods, tappets, pistons, connecting rods and bearings should be put away in suitable boxes. Disassembled parts have to be cleaned and thoroughly checked for the following: Sliding and rolling surfaces for wear and freedom from scoring marks, all metal parts, particularly castings, tempered parts and welded joints as well for cracks and corrosion, and rubber parts for suitableness. As a rule, all gaskets and tab washers are to replaced upon reassembling. When disassembling parts, attention has to be paid to the arrangement of lock-washers on screws and nuts, spacing washers, gaskets, rubber mounts and so on. If necessary, mark mating parts in order to guarantee correct assembly.
