Why does a moped not go faster than a scooter?
Most of the times a moped is restricted from going faster than it could and that is due to many factors. One of these is to protect the environment better and to do that, scooters use a catalyst that is used on the exhaust. This catalyst doesn’t directly restrict a moped’s power but those that tune mopeds say that you should remove it anyway.
Why does my scooter engine slowly stop running?
When the engine is cold and the valve adjustment is too tight, but not so tight as to keep the exhaust valve open, the engine will start. As the engine warms up and the valves and rocker arms expand due to heat, the valve is forced open and cannot close. You then have no compression and the engine stops running.
