Question about 2003 Yamaha V Star 1100 Classic
Posted by Anonymous on
Hi, Anonymous and the usual suspects are:
1. Spark plugs in bad condition or have an improper gap or are partially fouled.
2. Spark plug cables in bad condition.
3. Battery nearly discharged, should have 12.5 volts.
4. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Throttle controls not adjusted correctly.
6. Water or dirt in the fuel system.
7. Water or dirt in the carburetor.*
8. Intake air leak.
9. Fuel tank vent hose and vapor valve plugged, or fuel line closed off, restricting fuel flow.*
10. Enricher valve inoperative.*
11. Engine lubricant to heavy (winter operation).
12. Ignition is not functioning properly (possible sensor failure).
13. Faulty ignition coil.
14. Valves sticking.
* Carbureted models.

Perusal of a parts manual shows the bulbs to be in sockets with wires hooked to them which press into the outer back of the speedometer head, remove the offending socket (the one on the top, the other 4 are the function lamps I previously mentioned) by gently pulling it outward, the bulb will slide out for replacement.
Have fun and good luck.

Sounds like your carb jets may be partially plugged, common if they are stored incorrectly, The choke circuits on these carburetors work on manifold vacuum and if you throttle the bike while trying to start it you will lose the choke affect. if they are partially plugged the only good way to fix it is to pull the carburetors and clean them. I would advise checking out www.roadstarclinic.com is a great source of information for the yamaha star line of motorcycles.

1) Make sure your fuel petcock is closed, then detach the gas line coming off it (left underside of tank)
2) Remove the back seat (single acorn nut on rear fender)
3) Remove the front seat (two allen bolts at the back of seat)
4) There are two metric 12mm bolts under the front seat that hold the tank down. Remove them. The tank should be sitting loose on bike, but connected by some wires
5) Disconnect the white wiring harness under the bike. Tank is now totally free to remove.
6) Pull tank up and back at the same time, it will slide off the two rubber mounts at the front.
