SOURCE: misfiring at speed on gilera 200 scooter

This sounds more like a lean fuel condition than ignition. If it was stored over the winter without the gas being drained or a fuel stabilizer being added, you'll likely have varnish build-up in the fuel system that is not allowing sufficient fuel flow.  If your engine is fuel injected, it's likely your injector is partially clogged.  If it's carbureted, your carb jets may be partially clogged or your carb float may be sticking and not allowing the needle valve to fully open.  Fill the gas tank with fresh gasoline, but leave enough room for a can of Sea Foam.  The Sea Foam may be able to break up the deposits and allow fuel to flow again.  However, there's no guarantee and the fuel system may have to be disassembled to be cleaned.

ALWAYS have a fire extinguisher on hand when working on carburetors. Drain the carburetor. There should be a plug on the bottom of the carb float bowl. Remove the plug then replace it after the fuel drains. Remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the air screw on the outside throat of the
carb and spray into the screw hole as well. Be sure to put the air screw back in. IMPORTANT > do not tighten this adjuster down. Only screw it in until it LIGHTLY seats. Now turn the air screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine.
Can I get a “very helpful” rating on this answer?

SOURCE: peugeot jet force 50 engine cuts out on overrun

when the engine dies pull out the spark plug and earth the plug on the metal part and turn it over dont hold the spark plug as you will get a shock if the plug sparks you know the ignition system is working.if you have no spark do a compresion test to see if there is a problem with the engine.if that ok you will have a fuel problem make sure the breather on the fuel tank isn blocked or trapped.

Bike starts Ok runs for 3 mins then stops. seems to run longer on full throttle, when throttle is shut, bike stops as if running out of fuel


Hi, Raymond the following applies to carbureted also fuel injected models and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Air/fuel mixture screw improperly adjusted.
10. Accelerator pump damaged or not working.
11. Water or dirt in the fuel system, carburetor or filter.
12. Restricted, blocked or kinked fuel line.
13. Fuel tank empty.
14. The gas cap is not venting properly or fuel tank venting system blocked.
15. A failed fuel pump, pressure regulator and or fuel injectors.
16. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
17. Needle and seat stuck closed in the float bowl.

has the bike been sitting for some time? Sounds like a classic case of gummed up low speed jets in the carbs. Pull the carbs and clean then out.

Engine starts and idles perfectly, but as soon as throttle is applied engine cuts out and dies.any ideas??


Howdy: Could be the floats. Idle good but rev it up and the gas goes lean. Use quick start sprayed in the air cleaner area and see if the bike will rev. If so check out the float adjustment. Could be a stuck needle to the floats shut off. Good luck - Doug

Sounds like you have a fuel delivery problem. First check to see if there is a inline filter from the fuel tank to the carburators that is partially plugged. If not, you will have to remove the fuel valve from the fuel tank and clean the screens on the fuel pick-up tubes. The only other thing that would cause a fuel delivery problem would be the vacuum line from the carburators to the fuel valve has a split causing insufficient vacuum to open the fuel valve.

Starts well,runs wellfor five mins but then cuts


My first guess would be the fuel filter. It is probably almost completely plugged.
