Hi, i have just bought my first scooter and i am enjoying it very much. But i seem to have a problem with it just after startup.
My scooter is a Keeway Zahara 125 (gy6 engine) with about 350km on the clock. When i electric start it from cold, i have to give a little twist on the throttle to get it going (which the manual says is normal), it idles fine for about 30 seconds, then the idle dips and goes so low it will stall.
If i keep the throttle twisted a little it keeps going, then after about 2 minutes it idles fine and then doesn't miss a beat the whole journey. If i stop it when hot and restart it, it will start with just the electric starter (no throttle needed).
I have searched and done most of the things suggested, changed out the cheap Chinese plug for a Ngk one, adjusted the idle screw, adjusted the valves to a 0.04 clearance, and i have tried adjusting the fuel/air mix screw. All of which haven't solved the problem.
I can hear the auto choke working just after start up, but it still seems to dip and stall.
Any help would be great.
