i will ride it for 5-10 mins and will just slowly start to die and if i dow shift it will rev up as it shuld but no matter what i do with the gas it just slowly dies and then i will let it sit for a little while and it will start again. but its really annoying since its a pull start since i also am wondering why my electric start doesnt work if i put a wire directly from a battery to the starter and it doesnt spin does that mean the starter is fried or do i need to ground it a certain way or what should i do.
