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

0

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.

To install this needle and jet kit: • Remove carburetors from the engine per Yamaha shop manual procedures. Note: Always perform internal carburetor work in a clean area. • Remove the vacuum slide from each carburetor. • Remove the OEM needle, spacer and washers, noting order of assembly. (Note; the washers are used as shims to raise the needle, each is equivalent to ½ clip position, use these to fine tune the needle) • Counting from the top to the bottom, install the new Baron needle clip on groove #4 of the replacement Baron adjustable needles. The top is the blunt end of the needle. • Reinstall the OEM spacer and washers as shown in the figure below. • Reinstall the vacuum slides along with the diaphragm spring and reattach the diaphragm covers Note: Verify that the slides maintain their full range of movement! • Drain the fuel from the float bowls and remove the bowl covers. • Remove the OEM main jets and replace them with Baron’s supplied Mikuni main jets. Install the “base setting” main jets as indicated above. NOTE: V-Star 1100 carburetion runs staggered jetting! Make sure the front cylinder’s carburetor gets the larger main jet (numerically), and the rear cylinder’s carburetor gets the smaller main jet . Important! Extra jets have been included in your kit. These will help you fine-tune the carburetors for changing conditions. These conditions include climate and weather patterns in your area as well as exhaust equipment on your motorcycle. Barons determines the jet and clip recommendations that best suit your average riding conditions based upon information supplied to us at the time of your order. Changes in weather, altitude or modifications to your exhaust system may require jets other than those supplied. • Thoroughly clean the inside of the float bowls prior to reinstalling them. 311 #1 Industrial Way – Fallbrook, CA 92028 – USA Phone: (760) 731-1200 Fax: (760) 731-1284 E-mail: tech@baronscustom.com Website: www.baronscustom.com Included in this kit: (4)Mikuni main jets #107.5, 110, 112.5, 115, (2) titanium needles, (2) clips, (8) cap-head allen screws Tools required: 3-4-5 mm allen wrenches, 10&12 mm sockets, 10mm end wrench, phillips & flat screwdrivers, pliers, drill.

You want a big cruiser but you don’t need a large 1500 cc behemoth that weighs close to half-a-ton fully loaded. You want something you can cruise down the boulevard on but you want to be able to handle a corner or two. You want classic styling but you insist on reliability as well. If these are your guidelines, then Honda and Yamaha might have what you’re looking for in the guise of the Honda Shadow American Classic Edition and Yamaha V-Star 1100. Shadow ACE 1100 The ACE and V-Star have a few things in common: Both sport requisite V-twin powerplants (75° for the V-Star and 45° for the ACE) and both possess typical Japanese refinement. Aside from these similarities, the two rides are very different machines. While both machines are shaft driven, the ACE uses the shaft housing as the swingarm. Although this arrangement is effective, it’s a bit lacking style-wise. However, the whitewall tires and the classic fenders and tank help to create a traditional design that turns heads when you’re out and about. The V-Star uses a different approach, utilizing a pivoting sub-frame design with a hidden mono-shock that keeps the lines fluid and consistent with the rest of the bike. Although this beast isn’t equipped with whitewall tires, it still cuts a graceful, glittering profile. The only flaw we noticed was the small headlight that

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. RULE OF THUMB: high altitude or high temperatures  choose leaner carburetor adjustment low altitude or low temperatures  choose richer carburetor adjustment * WARNING * -ONLYUSE PREMIUM – GRADE GASOLINE ROZ 95 MIXED WITH HIGH – GRADE TWO – STROKE ENGINE OIL . OTHER TYPES OF GASOLINE CAN CAUSE ENGINE FAILURE , AND USE OF SAME WILL VOID YOUR WARRANTY . -ONLYUSE HIGH – GRADE 2- STROKE ENGINE OIL OF KNOWN BRANDS ( I . E .SHELL ADVANCE RACING X). -NOTENOUGH OIL OR LOW – GRADE OILCAN CAUSE EROSION OF THE PISTON . USING TOO MUCH OIL , THE ENGINE CAN START SMOKING AND FOUL THE SPARKPLUG . -INTHE CASE OFA LEANER ADJUSTMENT OF THE CARBURETOR PROCEED CAUTIOUSLY . ALWAYSREDUCETHEJETSIZEINSTEPSOFONENUMBERTOAVOID OVERHEATING AND PISTON SEIZURE . 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
