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.

1. The Stage IV controller can be mounted in numerous places. Placement depends on personal preferences. Only mount in locations where no damage may occur from sharp or hot objects. 4. Start the UTV and in approximately four seconds the lights on the Stage IV controller will be visible. With a proper install, you should see lights going from side to side on the controller. This will last approximately eight seconds and then will stop. After lights have stopped going side to side, you will notice a great light on the left side of the controller. When you rev the motor, lights will increase across the controller and even change colors. 5. Double check all fasteners and connections. 7. The Stage IV controller has been programmed for ultimate performance when using Trinity Racing’s Stage IV exhaust system and Powerflow intake system on an otherwise stock engine. Different products, modifications, or other conditions may require additional adjustments. Please refer to Basic Tuning Adjustments and all final fuel adjustments are the customer’s responsibility. 8. You are now ready to ride! Enjoy your new Stage IV fuel management controller!

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

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.

1. Begin by removing both side compartment covers. The RH compartment cover requires the use of the ignition key for removal; the LH compartment cover is secured by a large Phillips screw. Once you’ve removed the LH cover, place the Phillips screw back into the hole in the frame (so you don’t misplace it) and set both covers aside. In many applications, you must remove the upper exhaust pipe (from the rear cylinder), and loosen the other pipe, to remove the inner parts of the RH side compartment cover (see below). Before attempting step #2 below, try step #3 first… depending on the brand of exhaust pipes you have, you may be able to avoid removal in step #2, if you are successful with step #3 first. Some brands of exhaust pipes provide access to the fasteners securing the RH side covers, eliminating the requirement to remove pipes for rear suspension access. 2. Remove the rear cylinder’s exhaust pipe. To do so, remove the two Allen nuts on the exhaust header, where it attaches to the engine, using an 8mm Allen wrench. Most often, this goes much more smoothly if you first spray the inside of the allen nut with a penetrating lubricant like WD-40. Remove the black acorn nut from the discharge end of the exhaust pipe (under the upper exhaust pipe, near the discharge end of the pipe) using a 12mm open-end wrench or socket. You’ll find a black metal spacer, through which the bolt goes, that is pressed through the rubber grommet. To avoid the potential of having it fall out unnoticed, remove it and place it aside with the nut. Remove the black bolt from the pipe just aft (to the rear) of where the pipe enlarges and above the pipe. This is actually a bracket that holds the two pipes together at a joint. Loosen the bolt using a 12mm socket, then slide it back onto the pipe you’re removing. Once you have the pipe off of the bike, the clamp will be loose. Be sure to keep it with the pipe, along with the rest of the removed parts. Loosen the pipe from the front cylinder BEFORE trying to remove the pipe from the rear cylinder. By loosening the header nuts on the pipe from the front cylinder, and removing the two black Allen bolts (6mm Allen wrench) under the forward pipe that attach it to the frame, you will be able to remove the rear pipe. There are more spacers in grommets where the 6mm Allen bolts secure the lower pipe to the frame (like those used in the rearmost connection o

1. Wash engine sidecase to remove any dirt, grease, oil, etc. 2. Clean engine sidecase and the CFC case guard with quick drying solvent such as electrical contact cleaner or brake cleaner 3. Apply an even layer of Permatex 16B silicone adhesive* to the backside of the CFC guard. This can be a messy job and most find the best tool to spread it evenly is your finger. It is suggested that you use a rubber glove to avoid skin contact. Try to get complete coverage free of voids and about 1/16-1/8″ thick 4. Align sidecase Guard with the engine sidecase, keeping the logo horizontal (if the Guard has one). Gently press on the engine sidecase. Once you feel that it is aligned and positioned properly, press with enough evenly distributed pressure to get an equal squeeze out of Permatex all around the perimeter. Don’t worry if you end up with excess. Excess adhesive can be cleaned up with a rag and mineral spirits or brake/contact cleaner. Let dry overnight 5. A couple of strips of masking tape can be carefully applied to assure the guard doesn’t move
