sooooo i bought this same make of moped from a friend´s dad thinking i could get a good deal. well he had told me that it was basically brand new, however there was a previous owner who supposedly had ran it out of oil and returned it to him. so my friend´s dad said an entire new engine was replaced. thinking the bike was pretty much brand new besides the body, i was thinking i was getting a good deal. noooooot exactly. the thing would break down on me typically once a week and now it´s been busted for the past 2 mths. because i don´t want to deal with him anymore and i can´t find one place in my area that services keeways. when i go to start it, it starts up great but then just idles and slowly dies, probably about 5 seconds later. i´ve been told it´s the piston? i really know nothing about any of this i would just really appreciate some help and maybe a recommendation as to where i could bring it to get fixed. i live in the grand rapids/holland area. thanks
