Take a look at the engine. If you stand on the side where the variator and the air filter are, to the left of the carburetor you will see a black cap-looking like part. its sitting on an oval-like cap which is held down by 2 or 4 bolts. You have to take the cap off, and you will see the mechanism for regulating the tention of the chain which drives the valves. From what Im thinking the problem seems to be in the valves knocking, which mostly happens due to the chain stretching out with time. Tighten the chain up a little bit, start the engine. As the knocking continues, turn it off and tighten again. repeat as needed.

I have a 4 stoke 50cc gy6 moped. Today I was going about 44 mph down a street when i got to a traffic light. It just turned off and I couldn't start it again. It turns on but i can't give it gas. help?
sounds to me like the breather tube came loose on the carb.they are bad to vibrate and pop off .this causes the engine to get to little gas and too much air which results in the engine cutting off when you try to give it gas.

How do you adjust timing on gy6 engine?
there is no adjustments for timing, you can set the cam gear and crank gear but you should not have to unless you had it apart, if you did have it apart yo uhave to line the T on the flywheel the fan blade is on with the mark on the engine block, make sure the bog hole on the cam gear is facing the front of the scooter and the 2 small holes are even with the block on both sides. the CDI controls timing advance and performance ones are available pretty cheap.
