Let's Talk 250cc to 300cc motor scooters

Most scooters need a minimum of 100 psi in compression in order to run start and properly. Compression should be checked when the scooter engine is warm. However, that's hard to do if your scooter is not running. So, just hook up a compression gauge and open up the throttle all the way. Crank the scooter until the needle on the compression gauge stops moving. This should take no more than 5 seconds. Very roughly, 100-125 psi is good, 125-150 psi is very good, and 150+ psi is great. If you don't have this level of compression, then you have bad valves and/or bad piston rings. If you want, you can add a teaspoon or so of oil to the engine through the spark plug hole. Then try the compression test again. If compression is higher, then it's likely you have bad rings. The oil will seal the rings and give you better compression. If compression is the same, then you have bad/misadjusted valves.

Some scooters take a mix of oil and gasoline. Be aware, however, that local laws may not permit this kind of engine in a gas powered scooter. The EPA has made laws about the kind of emissions even fuel-efficient scooters can produce, and luckily, major scooter producers like China largely heed these standards with commonly sold scooters.
