GAS Motorcycles - Page 5 - Recent Questions, Troubleshooting & Support
I bought a 2005 vercucci gas scooter , it had been sitting for 4years ,I can't get it to start and don't know where to begin
if it is a 2 stroke it depends if it is an fuel/ oil premix set up or meter oil jet
the metered oil jet has a low oil level unit that prevents it running when there is no oil to mix
next , not being used for so long , the crankshaft seals will be dry and not sealing properly and so compression will be well down as it needs those seals to be perfect to get the fuel mixture into the sump and set it for the compression stroke
next it most likely has a kill switch on the handles so make sure that it is operational
so first steps are to turn on the ignition, remove the plug , ground it out by placing the body on the engine and kicking it over
If it doesn't spark then why not would be a good place to start
My ts 510 is it self mixing oil to gas
so what is your problem?
many 2 strokes engines have a separate oil tank with a metering jet to get the correct fuel/oil ratio for any given throttle setting
with a distinct lack of details,to get a better answer you have to state all the details and exactly the problem you have
Lights come on strong, bike won't start. when i push the starter button and hold it down and then pull in the clutch a large banging sound comes from inside the right side of the gas tank.
Hi Noah, It's either fuel OR electrical, First check both spark plug and coil.. Pull spark plug out and visually inspect for any dirt touching both electrodes... Next, Plug the spark plug back into the spark plug lead and earth it to the motor(make sure the spark plug is touching metal)then try turning the motor to see if the spark plug is sparking...
Also the link below is a short YouTube video showing the right colour spark and it should spark over the top of the centre electrode,
How to check for Spark Plug Fire in any engine
If it does spark then it's a fuel problem. You need to pull your carby off and unscrew the bottom half from the top, 1st sign of a needle stuck inside the seat is a dry carby There you'll find the float, push the float up and down and see if the needle above the float slides up and down from the seat, If the needle stays up then it's stuck and NOT letting the fuel into the carby, Just pull it down with your fingers to loosen it up..I hope this helps.... CHEERS..
Do you mix oil with gas
Joseph, Only when engine is 2 stroke, or if it has oil injection you do not have to mix, the oil injection does this for the engine.

Whats making carb flood with gas after bike is started and runs just a min or so then gas runs out carb over flow hose. I have replaced carb float and jets are all clean.
Hi Paige, Seems like the problem is where the float and needle meet, The needle and seat let the gas into the bottom of the carby and as the gas rises the float rises as well pushing the needle up into the seat slowing the gas flow into the bottom of the carby.... As the motor's using the gas in the bottom of the carby the float's lowering and the needle lowers as well allowing gas into the carby, If the part of the float that meets the needle is bent down slightly it's going to let more gas into the bottom of the carb because it's not pushing the needle up when it should, YOU NEED TO BEND THAT PART OF THE FLOAT UP SLIGHTLY TO STOP THE GAS COMING OUT THE OVERFLOW.... I hope you know what I mean....CHEERS..
