St1100 hard starting when cold@
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 damaged or nearly discharged, should have 12.5 volts.
4. 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. Choke 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.

your carburetors need top be removed from the bike and supmerged in a big pot of yamaha carburetor cleaner . And then blow thew it with air hose (45-75) psi

Probably just something in the valve train, perhaps a slightly sticking valve. Once it warms up or gets the oil it needs, the problem usually goes away.

There is a proper way to start an engine. Most bikes have four controls to assist in starting.
