Carburetor adjustment Basic information about the original carburetor setting The original carburetor setting was adapted for an altitude of approx. 500 meters (1600 ft.) above sea level, and the ambient temperature of approx. 20°C (68°F), mainly for off-road use and central European premium-grade fuel (ROZ 95). Mixing ratio 2-stroke motor oil : super fuel 1:40 . Basic information of changing the carburetor setting Always start out from the original carburetor setting. Essential requirements are a clean air filter system, air-tight exhaust system and an intact carburetor. Experience has shown that adjusting the main jet, the idling jet and the jet needle is sufficient and that changes of other parts of the carburetor will not greatly affect engine performance.

NOTE: If despite a changed adjustment the engine does not run properly, look for mechanical faults and check the ignition system. Basic information on carburetor wear As a result of engine vibrations, throttle valve, jet needle, and needle jet are subjected to increased wear. This wear may cause carburetor malfunction (e.g., overly rich mixture). Therefore, these parts should be replaced after 1000 hours of using. Idling range – A Operation with closed throttle valve. This range is influenced by the idle adjusting screw 1 . Only make adjustments when the engine is hot. The idling speed can be changed by turning the idle adjusting screw. Turning it clockwise produces a higher idling speed and turning the screw counterclockwise produces a lower idling speed. Opening up – B Engine behavior when the throttle opens. The idle jet and the shape of the throttle valve influences this range. If, despite good idling-speed and part-throttle setting, the engine sputters and smokes when the throttle is fully opened and develops its full power not smoothly but suddenly at high engine speeds, the mixture to the carburetor will be too rich, the fuel level too high or the float needle is leaking. Part-throttle range – C Operation with partly open throttle valve. This range is only influenced by the jet needle (shape and position). The optimum part-throttle setting is controlled by the idling setting in the lower range and by the main jet in the upper range. If the engine runs on a four-stroke cycle or with reduced power when it is accelerated with the throttle partly open, the jet needle must be lowered by one notch. If then the engine pings, especially when accelerating under full power at maximum engine revs, the jet needle should be raised. If these faults should occur at the lower end of the part throttle range at a four-stroke running, make the idling range leaner; if the engine pings, adjust the idling range richer

Repair manual KTM 250 / 300 / 380 Art No 3206004 -E 2-2C main jet jet needle jet needle air control screw idle adjusting screw idle jet throttle valve Idling range A Operation with closed throttle valve. This range is influenced by the position of the air control screw 1 and the idle adjusting screw 2 . Only make adjustments when the engine is hot. To this end, slightly increase the idling speed of the engine by means of the idle adjusting screw. Turning it clockwise produces a higher idling speed and turning the screw counterclockwise produces a lower idling speed. Create a round and stable engine speed using the air control screw (basic position of the air control screw = open by 1.5 turns). Then adjust to the normal idling speed by means of the idle adjusting screw. Opening up B Engine behavior when the throttle opens. The idle jet and the shape of the throttle valve influences this range. If, despite good idling-speed and part-throttle setting, the engine sputters and smokes when the throttle is fully opened and develops its full power not smoothly but suddenly at high engine speeds, the mixture to the carburetor will be too rich, the fuel level too high or the float needle is leaking. Part-throttle range C Operation with partly open throttle valve. This range is only influenced by the jet needle (shape and position).

If the engine runs on a four-stroke cycle or with reduced power when it is accelerated with the throttle partly open, the jet needle must be lowered by one notch. If then the engine pings, especially when accelerating under full power at maximum engine revs, the jet needle should be raised. If these faults should occur at the lower end of the part throttle range at a four-stroke running, make the idling range leaner; if the engine pings, adjust the idling range richer. Full throttle range D Operation with the throttle fully open (flat out). This range is influenced by the main jet and the jet needle. If the porcelain of the new spark plug is found to have a very bright or white coating or if the engine rings, after a short distance of riding flat out, a larger main jet is required. If the porcelain is dark brown or black with soot the main jet must be replaced by a smaller one. mixture too rich: too much fuel in proportion to air mixture too lean: not enough fuel in proportion to air 1 2 OPERATING RANGES OF THE CARBURETOR 2-3C Carburetor adjustment Basic information on the original carburetor setting The original carburetor setting was adapted for an altitude of approx. 500 meters (1600 ft.) above sea level, and the ambient temperature of approx. 20°C (68°F), mainly for off-road use and central European premium-grade fuel (ROZ 95 MOZ).

Vengeance Maxis • Vengeance Raven • Vengeance Banshee • Vengeance Whiplash • Hotrod Drifter • Hotrod CalChop • Hotrod Teacher • Hotrod Bone Shifting Gears Starting off and changing gears requires coordination of the clutch and throttle and gearshift lever. If you don’t do things right, the amount of control you have over the bike is lessened. To start off, pull in the clutch, shift into first gear, roll on the throttle a little, and ease out the clutch. You will become familiar with the friction zone (that’s where the clutch begins to take hold and move the bike), and you add a bit more throttle. You don’t want to stall the engine, nor do you want to over-rev it. There’s a sweet spot in there; find it. Shift while traveling in a straight line. Shifting in a curve is not good practice, and something to be avoided. Become familiar with the sound of your engine, so you can tell when you should shift without looking at your instruments. When you downshift to a lower gear, you should (in one swift, smooth movement) be able to squeeze the clutch, rev the engine a little to let it catch the lower gear smoothly, and shift down. When you come to a stop in traffic, leave the bike in first gear with the clutch disengaged (just in case you want to accelerate out of there in a hurry). Who knows what may be coming up behind you. Braking Don’t ever forget: The front brake on your motorcycle can supply as much as 70 percent or more of your stopping power. The single most important thing you can learn about braking is to use that front brake every single time you want to slow down. Turning When you are riding along the road, you lean a motorcycle into a turn. Learning to lean is an essential part of riding a motorcycle. It is a normal function of the bike when you are changing its path of travel – and quite different from turning the steering wheel of your car. To get the motorcycle to lean in a normal turn, press the handlebar in the direction of the turn and maintain slight pressure on that handlebar to take you smoothly through that particular turn. In other words: press right to go right; press left to go left. Your instincts to keep the motorcycle on a smooth path while keeping it from falling over usually take care of this without you even noticing it. (Demonstrate to yourself how a motorcycle moves by pressing a handlebar slightly while traveling in a straight line. The motorcycle will move in the direction of the handlebar you pushed.) • Slow down before you enter the turn; look as far ahead as possible through the turn. • Keep your feet on the pegs, and grip the gas tank with your knees. • Lean with the motorcycle; don’t try to sit perpendicular to the road while the motorcycle is leaning over. • Keep an even throttle through the turn, or even accelerate a little bit. Checking the Bike before the Ride It’s not fun to have things go wrong on a motorcycle, but if you spend a minute before you go off on a ride, you can increase the chances that nothing will.

YAMAHA V-Star 1100 Carburetor Bowl Screw Repair and Removal After Stripping and Pilot Cap Removal

Filed Under (Yamaha) by admin on 19-01-2012

When I first started working on bike many years ago, I learned the danger of stripping the heads of Philips screws when removing or installing them on motorcycles. I remember the two worst screws were the casing side-cover aluminum screws and carburetor bowl screws. I think I tried every method of screw removal after they were stripped. Vice grips, better tipped screwdriver, hammer, drill, and other tools were used. One way I learned to remove stripped screws is to re-make the Philips head into a flathead screw. Cutting a slot in the top of the screw and then use a flat-head screwdriver to remove the screw. On some parts this technique can work, other parts and screws it may not. The Philips screws on the bottom of the V-Star carburetor bowls are VERY prone to stripping. In fact, I will not start a carburetor cleaning without new hex head screws to replace the original Philips bowl screws. Replace the bowl screws for yourself if you keep the bike, or for the next rider that will appreciate the hex-head screws when they clean the carburetors. Not many other parts on a V-Star have screws that are prone to stripping. This documentation is to help riders with motorcycle maintenance. Some riders will find themselves with the problem of removing stripped screws. A carburetor cleaning can quickly double in time when you realize the hardest part of the job is removing bowl screws after they strip. And then realizing you do not have the replacement hex-head screws available and must now go to the hardware store.

Intake Manifold: 1. Install MAP sensor in Mikuni manifold (Twin Cam only). 2. Attach the Mikuni manifold to the engine. Align the manifold before tightening the bolts. The flange surface of the Mikuni manifold should be parallel with the front of the engine’s cam cover. Use a level or angle meter to check this. Tighten the manifold bolts. 3. Attach the rubber flange to the Mikuni manifold with the furnished 5/16″x3/4″ bolts and washers. Choke Cables: Mikuni & Harley-Davidson Route the cable with largest radius bends possible. Check the cable for free-play after installation. If there is no free-play, the engine may run rich and deliver poor performance or low fuel mileage. Harley Cable (Twin Cam Kits: 42-19, 45-4) : 1. Remove the Harley choke cable from the stock carb. 2. Remove the spring and plunger from the cable. 3. Remove the spring and plunger from the Mikuni. 5. Install the Mikuni spring and plunger onto the Harley choke cable. Change nothing else; be sure to use the Harley plastic nut, not the Mikuni nut (See Figure 1). Total Kit Installation Instructions The HSR series carburetors are precise yet durable instruments; however, like any other piece of fine equipment, they require correct installation and reasonable care to assure optimum performance and long life. Extra time spent during installation will pay off in both short and long term performance and reliability. This Mikuni HSR carburetor kit is designed to be a bolt-on application, and as such, is set-up and jetted properly for most applications. However, since Harley-Davidson motors are often highly modified, alternate tuning settings may be required. The Mikuni Tuning Manual helps make jetting alterations and adjustments an easy matter. NOTE: Carburetor Kits not designated as C.A.R.B. exempt, are not legal for motor vehicles operated on public highways in the state of California, or in any other states and countries where similar laws apply. WARNING NOTE: NOTE: WARNING CAUTION NOTE: NOTE: TK-2 6. Install the new assembly into the Mikuni carburetor. Be careful to only gently tighten the plastic nut. 7. Loosen the knurled plastic friction nut behind the choke knob and check for free-play (see Figure 2). Figure 1: Harley nut with Mikuni spring & plunger Figure 2: Choke cable adjustments Mikuni Cable (Evo Kits: 42-8, 45-2 & 45-3) : 1. Remove nut, spring and plunger from the Mikuni. 2. Install the nut, spring and plunger onto the cable. 3. Install the assembly into the Mikuni HSR carburetor. Be careful to only gently tighten the plastic nut. 4. Check for free-play. Adjust the cable as necessary. An optional choke cable mounting bracket is included in the Evo kits for custom installations. Carburetor Installation: 1. Insert the carb fully into the rubber flange, align with engine and tighten the clamp. 2. Slip the fuel hose onto the carburetor’s fuel fitting and secure with the enclosed hose clamp. NOTE: Some Twin Cam installations may require removal of a small amount of fin material from the cylinders to clear the float bowl. Throttle Cables The HSR carburetor uses stock 1990 and later Harley- Davidson cables. However, if your Harley is fitted with some other carburetor, you may need to purchase a set of cables. See your dealer for the correct cable set. 1. Route the throttle cables with large radius curves and so they do not interfere with other components. 2. Screw the cable adjusters together to make them as short as possible. 3. Connect the “close” cable first (see Figure 3). 4. Install the “open” cable next (see Figure 3). 5. Adjust the opening cable until the slide can be opened fully. Snug the adjuster lock nut. 6. Turn the handlebar to the right and adjust the throttle free-play with the closing cable adjuster to approximately 1/8″ (see Figure 4)
