Improving the acceleration on a Moped

    My moped Yahama Aerox is quite slow at getting up to speed or accelerating. Its top speed is fine but have found it dangerous at times when trying to get past traffic quickly or buses just pulling away from a stop to the point where it can leave you hanging out there a while.
    Is it easy/hard enough to get acceleration improved?

    There are a couple of things you can do to improve acceleration and top speed on a moped but you're very much limited to the engine.

    The first is to get it unrestricted - most 49cc mopeds are restricted to allow a driver with an M class license to drive them - if you've got an A/A1 you should be able to get this restriction removed in any garage - most people do this whether or not they've got the license. This should give you a little extra power.

    You can also change the exhaust for a more hi-performance one - these can cost quite a bit and you should get some results.

    Overall you should get a bit of a power bump but nothing spectacular.

    also,have a look at your throttle cable,they have a tendancy to go slack over time resulting in a loss of initial acceleration. got mine tightened up before and she was brand new,away like a hare at the lights:D

    Or try getting the standard exhaust cleaned out. Crud builds up in two-stroke exhausts eventually and saps the power.
    It's possible the drive belt is worn out and slipping under acceleration. If the revs shoot way up when you open the throttle, but nothing much happens, it could be slipping.

    In Cavan there was a great fire / Judge McCarthy was sent to inquire / It would be a shame / If the nuns were to blame / So it had to be caused by a wire.

    You can usually get alternative sets of weights/ramp for the CVT pulley too to make better use of a new exhaust

    Exhausts are pricey. try looking to see if the restrictor is just a large washer blocking most of the airflow in the exhaust. it'll probably have to be rejetted after removing that though...

    Alternatively, use better quality two-stroke oil and having it serviced!
