SOURCE: My 1999 gilera runner 50cc cut out on me,now it won't start

Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it and clean it. With the gas valve turned off, does gas still get past the valve? If it does, then you need to replace the valve. Re-mount the bowl, ( not all bikes have a water trap bowl ). Always turn the gas off when not riding the bike. If the valve will not fully shut off the gas then a leak-down condition can occur and cause gas to get to the exhaust pipe.

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and 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 idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster 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. This process should get you back on the road.

Please rate this solution. Thanks!

SOURCE: Gilera Runner very difficult to start cold,then cuts out when hot

to check the electric choke..take it/off out of carb & unplug it. then get 2 short lenghts of wires, strip both ends...shove one end into the choke plug teminals(one in each hole) .then put one of the striped ends of thewires on a charged battery(one on the positve & one on the negitvie terminals) .keep them on for about 5 mins & you should see the choke head extend (you could always mesure it befor you put to battery & check in 5mis to see if extened!!) this will tell you if its working!!...if its not working this will explane why you have trouble starting from cold!! also sounds like the main jet is blocked...this is found by taking of the float bowl (as you may know!)it will prob be the small hole up the middle of the jet that is made up with muck!!...try sticking a strand of a wire brush up/threw it...also it sounds like the exhaust is leaking round the maifold..will have to take exhaust of & check if it need a new gasket..or resealing!!(does the exhaust blow?. this is good way to tell if it is leaking(put a rag/palm of hand over end of exhaust & you should beable to hear it blowing. ...hope this helps....Howard

If it is water cooled first check the coolant level also the temp sensor switch on the engine that turns on the fan also the temp problem could be a bad thermostat or a bad fan the engine cutting out could be due to over temp I have also seen this happen due to a bad kick stand safety switch if yours has one

Overflow leaking

From your description (keeps overflowing,spark plug always wet), it sounds like it's flooding.
Because of the overflowing, possibly your float is set too high, or some crud is lodged between the float needle valve and it's seat, not allowing it to seal shut when the float bowl is full, then flooding the carb's mixing chamber.

Sounds like you have a problem with the choke on the carburetor. I'm not familiar with this scooter. Does it have an automatic choke or manual? Is it possible for you to post a video of the problem? I will know better what the issue is after hearing it.

Everyday when i leave my gilera runner vx i have to let it warm up as if i try drive straight away it bogs and cuts out what is the problem?

The choke maybe cutiing out too soon or it is the air temperature that is cool.
Let it warm up for a few minutes before riding off.

Yours is not a battery or oil problem. Rather, it is a fuel delivery problem, probably not enough. Possibly from a dirty carb OR, could it be cold and you need more choke until it heats up? You replaced your plug with the proper value plug, right???

First stop is: Is your fuel fresh? If not, burn up what you have. You could drain it but I don't recommend this procedure. What will you do with what you drain out? Do what ever you need to do to get it out of the tank. Do you ride daily or does this bike sit for periods? I suggest you use a fuel system cleaner - fuel injector cleaner is one option - use no more than the container tells you to use. Another thing, if you don't ride frequently, consider protecting your clean system with a fuel stabilizer, STA-BIL is one brand. Get it at the auto parts place or from your Gilera dealer. While there, ask them for any recommendations they may have. Questions there are free and always based on their best knowledge of their own euipment.
