Hi Anonymous, if you have a carburator the usual suspects are:
1. Damaged or restricted fuel tank venting system (gas cap).
2. Inlet system air leak.
3. Vacuum piston malfunction.
4. Accelerator pump leaking or no output.
5. Plugged bowl vent.
6. Fuel level (float chamber) too low.
7. Restriccted fuel supply passages.
8. Plugged jets or passages.
9. Worn or damaged needle or needle jet.
10. Enrichner valve not seated or leaking.
Good luck

If the engine is not spitting or sputtering, the plugs are fine. If they were fouled, the engine would not run well at all. Probably just the fuel is stale. Today's fuels don't hold up in the tank like they use to do. Once you get that fuel run out and put some fresh fuel in the bike it should run like it always did before the surgery.

The carburetor works off of vacuum. Check the diaphram for holes. This will prevent the slide from fully opening, and cause a big loss in power.

If your engine is equipped with a carburetor, check the accelerator pump. Remove the air cleaner cover and the air filter. With the engine OFF and the petcock on, crank the throttle to the wide open position. Watch the small brass thing just inside the mouth of the carb as you do this. You should see it squirt a stream of fuel into the carb. If not, you need to rebuild the accelerator pump in the carb.

If it's fuel injected, you'll have to take it to a dealer.

Good luck

This may been an ignition module or a MAF sensor, this car may need to be diagnosed using a OBD I computer code reader to accurately diagnose the problem.
