This can be for a few reasons such as air intake restrictions poor or dirty fuel ,cabs blocked or some electrical problem My starting place would be fuel , empty your fuel tank and drain your cabs check any fuel filters , if fuel in your tank is muddy looking or there or there is excessive rust build up in your tank this can also contaminate your carbies causing blockages as well as making the fuel a poor quality and hard to be combusted properly resulting in poor revving ability , if the fuel checks out ok you still need to consider blockages in the carbs so start off with a good carb cleaner and spray it into the fuel line intakes on all carbs and air intake areas as well as removing the float chamber covers on the bottom of your carbs and spraying everywhere with carb cleaner replacing the fuel filter or installing one is a good idea . the air intake filter needs to be checked and cleaned making sure its in good condition if not replace it , Next you will need to remove and clean your spark plugs and inspect them for discoloration as in spark plugs that are black and sooty looking means the fuel is not getting burnt sufficiently and is called to rich or if the plugs show a white pale coloration this can mean lack of fuel is been delivered and is called to lean, if plugs are in a poor condition replace them . These jobs can be easy done by your self and can fix many problems but if you have tried these methods or found them to difficult and nothing has improved its time to get some expert to find out and possibly fix your bike ( bike shop machanic )

Hi, Steiner if you have changed your fuel delivery system, air filter size or flow rate, mufflers or exhaust system your carburetors need re-tuning and if your fuel system (gas tank, filters, fuel valve and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. You engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" your not getting enough fuel.
1. Closed to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. Wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark gray, engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.

Check valve clearance. If no clearance then not enough compression to start. Check for spark and that carb is supplying fuel.

You should have slightly over 14 volts if you have a good battery and clean connections. The mystery wire with no power on it until you complete the circuit is likely power wires after you turn on your ignition to power them

First:It is draining amps,bad rotor bushing (will touch the walls),bad brushes (lack of power).Last:Bad valves timing gets to increased force to crank.Cheers.

I'd check the oil pressure switch (cheap fix) if it has oil pressure. Have you topped up the oil too much from worry about the low oil pressure?

1991 Yamaha XT... | Answered on Oct 22, 2013


Your carburetor is most likely running lean. Get the jets cleaned (or heck, just replace the durn things while you're at it) and it should be fine.
Note: Most of the big-bore dual-purpose motorcycles come from the factory purposely jetted lean, no matter what manufacturer puts them on the street. This is to keep them from running at their full potential (which believe me, will peel your eyelids back). You will find that a simple rejetting with a slightly larger-than-factory-spec jet kit will make you want to kiss your mechanic when you get it back.

I would replace the HT cables and plug caps first to see if that fixes it.

1991 Yamaha XT... | Answered on Jan 25, 2011


I think I would start with the safety lock out switches ie does the bike have a switch that stops you from starting the machine with the kick stand down? Or the neutral safety switch or the kill switch.You are going to have to go and get a 12 volt meter or a test lamp and follow the power from the battery to the switch,out and in of these various switches.I agree 100% that this is electrical in nature.Don't forget to check the starter solenoid as well.Good Luck

No, it supposed to be 12 Vdc or a bit higher.
Check and fix your charger.

1991 Yamaha XT... | Answered on Aug 11, 2010


I'd come straight off the battery myself. Just remember to fit a suitable in-line fuse in the positive side of the circuit to prevent any future overloads or mishaps from causing avoidable damage elsewhere - blow the fuse and not something else.
A fuse of about 3 amps would probably suffice.
Hope this helps.

starter relay/solenoid stuck open and drained the battery. charge the battery and replace the relay/solenoid. Sometime you can tap on the relay lightly with a hammer and get it to unstick and work but it's best to replace it.
