Fuel mixture is too rich. The easiest way I adjust those is to have a friend stand in front of the scooter, holding the wheel and handlebars still while I lightly hit the throttle and at the same time, adjusting the fuel mixture screw on the carburetor slightly. applying the throttle harder while adjusting, you should feel the scooter gain or lose power.

sounds like you have too much voltage coming out from your battery, mabey a faulty regulator. The easiest way to test this, is to get a multi - meter, and check the volage output at the battery, with the engine running, at idle should read about 12.5 - 13 volts. Then rev the bike up, and seeif the reading changes, it should not go more than 13.8 or 14 volts max. If it does, then i say you have a faulty regulator/ rectifier.

You don't " get a cylinder cleaned ". Who ever says that doesn't know what he is talking about. I assume the engine is a two stroke. The gas/oil mixture should be 32 to1. That means 4 ounces of two stroke engine oil to one gallon of gas. If the scooter has an automatic oil pump be sure there is oil in the oil tank. It should automaticly pump the engine oil at the proper rate. If this is an older scooter, you could remove the cylinder head and de-carbon it and then check the exhaust port to be sure the port has not been made smaller due to carbon build up. The port should be about 1/2" tall and 1" wide. Also check and clean the air filter. If it is a new scooter is it still under warranty?
