you bike has points. check them and see if they are sparking and if they
aren't then go to your nearest moped dealer and get a new pair of
points. they are only like 10.00. if they are sparking check your coil
that might not be properly working all of the time. and if that is
working then get a new plug and plug wire. oh yea... bring your cooil to
the moped or motorcycle dealer nearest you an ask them to test it they
will telll you if it is working right or not.
hope this helps,
