My 2008 keeway 50cc scooter will not run faster then 15-20 mph on flat ground. it also bogs sometimes when it reachs that speed. where can I find a repair manual and wiring diagram for this scooter? o

That old gas had sediment in it and you need to remove the tank, fuel pump and filters and change them.

CHECK VOLTAGE WITH VOLT METER AND GAS/OIL MIX COULD BE RUNNING ROUGH

You have a bad ignition module.

Hopefully, one of these links will help.

Usually when you drive a bike it's very noisy and you feel vibrations through your body, this will prevent you from hearing a call ring or call vibration, that light on the scooter shows you when you get phone calls (is activated by the waves of the call you get on your cell phone).

if you look down from the handle bars to where your feet go you will see a little rectangle on the plastic, if you pop this off the VIN is underneath

I found that if I run 87 octane gasoline the engine accelerates up to full speed without the skipping and bogging down at any point it is running. It is worth trying. also try putting some "Sta-bil" fuel stabilizer in the gasoline - it has the ability to keep the carbureator cleaner. Not just during the time you are storing it, but rather all the time.

The thing with two strokes is that they smoke a bit under normal operation, and they smoke like mad if they haven't really been run for a period of time, I would advise you to run it for a while and see if that helps.

You should not need to adjust the mixture settings at all.


Hope this helps
