How much compression should a 50cc scooter have?
Most scooters need a minimum of 100 psi in compression to run start and properly. Compression should be checked when the engine is warm, but that’s kind of hard to do if the scooter is not running. So just hook up a compression gauge and open up the throttle all the way.Click to see full…

Performing the Compression Test The ideal pressures for an average 2 stroke dirt bike at sea level that is not heavily modified should be in the vicinity of the numbers below. A 50cc, 60cc, 80cc, 100cc, 125cc 200cc or 500cc should be able to squeeze out a reading of 120-190 PSI.Similarly, how do you fix a low compression scooter? You should have at least 100psi compression. If it’s lower than 100 psi, you can try and squirt a little oil into the cylinder and try measuring again. If the compression got much better you should change the piston rings. When did you adjust the valves last? Then, how much compression should a 2 stroke have? Check the owner’s manual of your bike for ideal engine pressure but generally speaking a healthy 250cc 2-stroke engine shows compression ranges from 170 to 240 psi and all other engine sizes between 120 and 190.How much compression should a 125 2 stroke have?A Brief Note About Compression Gauges – It bears noting that most compression gauges are made for automotive applications where V8 engines often have a swept compression volume of 700+ccs. Unfortunately, the average 125cc 2-stroke has a swept volume of about 70cc.
