Question

when i start it up it wont stay started i have to keep giving it gas.

Answer 1

Check the idle screw on the side of the carburator, you might need to screw it in, this will increase the engine speed.

Answer 2

In motocross, motorcycles are tuned in basic terms so that they are going to stall at idle.(2-strokes) although I don’t imagine you're in professional MX or you'll not ask. i'll anticipate you performed with the idle also. So..this can be many stuff. in accordance with what i understand, it truly is little, i might want first of all replacing the reeds; although in the experience that they provide the effect of being good. The reeds administration the gas bypass and are major to creating the motorbike run a peek performance. no matter if that is not the reeds properly, now you've clean reeds and also you recognize its no longer that ;-)

Answer 3

The air cleaner is clogged and has to be cleaned. Or the carburettor slowrunning jet is blocked and you have to accelerate to get the fuel through the main jet.

Answer 4

Fuel adjustment or you need to adjust the valves.If the intake valve is leaking you loose fuel.If the exhaust valve leaks you loose fuel and compression.The exhaust is the one that gives more trouble.

Answer 5

if its not the idle screw turn your air screw all the way in then turn it out a turn n a half if not that then make sure your choke is off
