Basic Tuning Adjustments 1. The following instructions are for basic fuel tuning. Modes 1,2, & 3 are allowing adjustments to increase and decrease the amount of fuel the engine needs. Modes 4 & 5 are for advanced tuning only. DO NOT change modes 4 & 5 when doing basic tuning! 2. To help understand how these modes work, you can think of them as if you were working with a carburetor. 3. Remember each time you push the MODE button you will be advancing to the next mode. Push the MODE button once and you are now in mode 1, push the MODE button again and you are now in mode 2 and so on. You only need to be concerned with modes 1, 2 & 3 for basic tuning. Modes 4 & 5 are for advanced tuning ONLY. 4. If you need to go back to the settings that were pre programmed when you purchased the controller, just look at the picture in each mode, the colored square represents where the settings were when you purchased the controller. 5. Looking at the controller you will see eight lights with numbers under them, this is what you need to look at when changing settings. The #1 light on the controller represents the leanest setting. TRINITY RACING DOES NOT TAKE REPONSIBLITY FOR DAMAGES THAT MAY OCCUR DURING OPERATION OF YOUR VEHICLE UNDER IMPROPER JET SETTINGS. IT IS THE FINAL RESPONSIBLITY OF THE OWNER/RIDER TO ADJUST JETTING TO SPECIFIC RIDING CONDITIONS AND ELEVATION BEFORE RIDING. WARNING! 1.877.FAS TOYS 2.Remove both seats 6. Re-install engine cover and seats. 6. Mode 1 green light represents idle & cruise adjustment (i.e. pilot jet). To adjust this setting push the MODE button once and then push the plus or minus buttons to adjust fuel as needed. 7. Mode 2 yellow light represents an additional amount of fuel added during acceleration (i.e. needle position). To adjust this setting, push MODE twice and then push the plus or minus buttons to adjust fuel as needed. 12 34 56 7 8 12 34 56 7 8 8. Mode 3 red light represents more fuel being added during full throttle (i.e. main jet). To adjust this setting push the MODE button three times and then push the plus or minus buttons to adjust fuel as needed. 9. If you are confident about your tuning skills and feel you need to adjust other parameters, see Advanced Tuning. 12 34 56 7 8 Advanced Tuning Adjustments 1. Advance tuning has two modes in which to adjust. They are called mode 4 and mode 5. In basic tuning, you are changing the amount of fuel that the engine receives, but with advance tuning, you will be changing when the fuel will be available. In each mode you can adjust how soon the fuel delivery occurs. 2. Mode 4 yellow light and blue light represent when the fuel delivery is available during partial throttle acceleration. To adjust this setting, push the MODE button four times and then push the plus or minus buttons to adjust fuel as needed. Only the yellow light will be changing.

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.

Jets: These are made in various sizes ranging from.099 inches to.1875 inches, the larger sizes being used only for racing or very high performance engines. The two sizes most commonly found on production cars are the.090 inch and the.100 inch. The size of the jet will be found stamped on the jet head. The figure “nine”wilt indicate that it is the.090 inch and the figure “one”will indicate the.100 inch jet. When tuninga production car the jets size should be checked to make sure that it is of the size recommended by the manufacturers. Centering of Jet: If for any reason, the jet assembly has been removed, it will be ne cessary to recenter the jet. First, remove the clevis pin at the base of the jet which attaches the jet head to the jet operating lever. Withdraw the jet completely and remove the adjusting nut and spring, then replace the adjusting nut, without its spring, and screw it up toits highest position. Slide the Set into position until the jet head is against the base of the adjusting nut. When this has been done, find out if the piston is perfectly free by lifting it up with the finger and allowing it to drop. If the piston is not entirely free, slacken the jet screw and manipulate the lower part of the assembly, including the projecting part of the bottom half of the jet bearing, adjusting nut, and jet head. Make sure that this assembly is now slightly loose. The piston should then rise and fall quite freely as the needle is now able to move the jet into the required central position. The jet screw should now be tightened and a further check made to determine that the piston is still quite free. When complete freedom of the piston is achieved the jet adjusting nut should be removed, together with the jet, and the spring replaced. Experience has shown that a large percentage of carburetors, which have given trouble has been due to the incorrect centering of jets. Jet Needles— These are made in a great variety of sizes, probably now well over two hundred and fifty, and each type of engine hasaneedlethat has been selected, after very careful tests have been carried out, to give the best all-round performance. Most manufacturers actually give three alternative needles for each type and size of engine, these needles clearly being listed by the manufacturer “Standard”, “Rich”or”Weak”and before tuning is started the needle, which is marked on the shank should be checked against the manufacturer’srecommendation to make quite sure that the right needle is fitted; this is most important.

This manual is intended as a guide for users of Mikuni carburetors who want to learn the adjusting method to the best performance from our products. In motorcycles, special tuning of the engine is now considereda routine practice. The arrows that appear in the drawings in this text show the direction in which air, fuel and an air-fuel mixture flows, respectively. ¢JAir Fuel “Mixture Mounting angle fore and aft inclination of the carb should not exceed approx Function of a carburetor The function of a carburetor is to produce combustible air-fuel mixture, by breaking fuel into tiny particles (in the form of vapor) and by mixing the fuel with air in a proper ratio, and to deliver the mixture to the engine. A proper ratio (mixture ratio or air-fuel ratio) means an ideal air-fuel mixture that can burn without leaving an excess of fuel or air, Whether the proper mixture ratio is maintained or not holds the key to the efficient engine operation, 2. Air-fuel mixture required by the engine (Fig. 1) The ratio of a mixture of fuel and air is called the mixture ratio or the air-fuel ratio and is generally expressed by the weight proportion. Theoretically, the amount of air required for complete combustion of 1 gram of fuel under normal conditions is

1. Make sure the ignition timing is correct 2. Adjust the valves as necessary to ensure proper operation 3. Run the engine to warm it up a bit 4. Adjust the float setting. To do this, remove the carburetors (leave the throttle cables attached), remove the bowl and turn the carburetor upside down (fuel will spill). The float should look like this: Adjust as necessary by bending the float support (#37 in Figure 1). Reinstall Installation and idle adjustment 1. First you must adjust the idle. It is acceptable per the manual to adjust the idle by using the idle adjust screws (11). This usually involves screwing them then backing out 1 to 1.5 turns. Or you can adjust looking at the sliders 2. If installing the carburetors: a. Remove the cover (2) b. Reomve the slider (3) c. Place the throttle cable through the guide (18) with the spring (4) on the cable. d. Route the cable through the slide catch (6) e. Insert the slide assembly into the chamber and make sure it easily slides up and down. Direct the needle (8) into the opening of the diffuser (angled side visible). f. Screw assembly together and verify via throttle movement that slide moves freely. Attach fuel delivery lines to (12). 3. Using the idle set screw (11) raise the slider so the lower edge is 1-2 mm. 4. Assemble to engine using the proper gaskets (paper – felt – paper). 5. Using the locknut (26) adjust the free play of the throttle cable (2-3 mm) 6. Adjust the idle mixture screw – turn in completely then out 1 to 1.5 turns. * Starting using the K68′s (cold weather) 1. Verify fuel flow. Apply choke (pull 52 in Fig1). 2. Using the ticklers (13) allow fuel to enter the bowl until fuel drains from (14) 3. With the ignition off, kick 1 or 2 times 4. Turn ignition on, and as soon as engine is warmed up (maybe sooner) push choke mechanisms to open choke Idle Adjustment (engine running and warm) 1. Remove one of the spark plug caps, and with the cap shorted, adjust (11) to decrease RPM’s to a point of being minimally steady. 2. Adjust the mixture (15) out until RPM’s decrease. Turn in until RPM’s increase slightly. Then turn in screws ¼ to 1/3 revoultion. 3. Do the same for the second carburetor with the first spark plug cap shorted. 4. With both cylinders, adjust each idle (11) on each carburetor the same amount each until it’s at a steady, minimal RPM. Use small changes. (at this point you can use your airflow tool to check). 5. Sharply increase, then decrease throttle. Then engine must return to low RPMs smoothly. If the engine goes below limits, readjust (11) from step 4. Synchronization of the K68 Note: Rather than using the opposite cylinder shorted to test the pull of the live cylinder carburetor, you can use something like a Twinmax connected to the test ports (27 Fig 1). Or, if you have a model without these ports, use a Synchrometer (Appendix 2) held against the face of the carburetor. These tools merely show airflow passing through each carburetor (which is dependent on the position and wear on the slide). If using these tools, it’s not necessary to do the following steps. You wil want to use a throttle guide (Appendix 1), to show airflow at various throttle settings. Using the flow meter of your choice make sure each carburetor is the same at the various throttle settings. 1. Place the motorcycle on the center stand ensuring the rear wheel is suspended 2. Make sure you have large area to work with (safety issues here) 3. Shift into the highest gear with the engine running 4. Short one spark plug cap to the cylinder (using a nail or something in the fins) 5. Increase the speed to 40-50 km/hr 6. Fix the throttle using the throttle (maybe using a throttle stop screw under the throttle housing). 7. Reconnect other cylinder and using the opposite carburetor determine the speed which should be the same as the first. 8. Adjust the position of this slide to achieve the referenced speed using the locknut at the top of the carburetor.
