help with running better

[zoeconner]

It starts great and runs great for about 15 min. After that the horse power drops out. Really bad! What should I try? Its been doing this for about two years now. wasnt a problem my son was only 3-4 and he didnt ride a long time. Now its a pain.

thanks

i am going through the same problem. everyone has narrowed my problem down to the stator going bad. i am about to order a new one, hope it works.

you did not change the oil. it is not lubricated
