To install, remove the stock carb per Yamaha shop manual procedures. Remove stock throttle cables. Install Mikuni HSR carb into intake manifold and tighten manifold clamp. Install new HSR series throttle cables and adjust cable slack per Yamaha shop manual procedures. Hook fuel line to HSR carb and fasten clamp.* Start motorcycle and fine tune HSR carb for proper running per supplied Mikuni tuning manual. *NOTE: Mikuni HSR series carburetors are designed for gravity-feed fuel systems. You should bypass your stock fuel pump and directly feed your HSR carb right from the fuel petcock. We have noted, though, that you may not be able to get good fuel flow from your Road Star fuel tank in low-fuel situations. You may run your stock fuel pump with the HSR carb, but to do so requires the purchase and installation of an adjustable fuel pressure regulator (set at 1/2 to 1 lb. of pressure). These are available from most auto parts stores. The stock carb has 2 wires running to the lower rear of the float bowl , these were for a carb warmer, they are not used in this application. Unplug these wires at the main wire harness and retain with your stock carb. The Road Star ignition system uses data from the stock throttle position sensor (TPS) to manage your ignition timing. It is necessary to give the bike this information. You may do so by removing the TPS sensor from the stock carb, leaving it plugged into the main wire harness (the sensor must be fixed to a closed-throttle position), or you may locate the plug for the TPS on the main wire harness and test the leads – you will find one ground, one with .5V and one with 1.5V. Connect the 1.5V to the ground and this will give the bike the same information as stock fully closed throttle. The output of the OEM fuel pump is too high and will cause fuel overflow in the HSR carb, resulting in a possible dangerous fire hazard

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.

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.
