l have (forgot the name but) a 125r and its a kick start and it has gas and runs for a while,but l cant keep it on for a long time.
it leaks allot of gas from the throttle.and l do not know how to work the throttle Valve.
i need to know step by step.
if l have to have it on choke or not.
turn the valve on or off.
please help
i got a race in 2 weeks.
yes its a 4 stroke.
and yeah l change the spark plug everytime l race.
do you have anymore tipps.

thanks.
i dont know how to use that thing that says FUEL.its on the left side of the bike. and l dont noe to put it pointing up or down.

if you have gas running out you need to take it off the bike and check everything. if it is coming from the bottom you need to tighten the plug on the bottom of the carb. l think it is a 15mm wrench. and if its a four stroke bike that should fix the problem. if it is two cycle which you need to add oil to the gas then you may need a new spark plug. l would change spark if l was going to race anyways and everytime before l raced if l was you. hope this helped
