Hello everyone I'm I'm need of some help. I recently acquired a kfx 50 for my son, not sure of the year model. I have been experiencing issues with keeping it running. I started having issues with keeping it started and it started to leak gas. So far I have had the carb, exhaust, jets etc cleaned and have stopped the leak and it's purring like a kitten while sitting still. As soon as you give it a bump it will die. Any idea on what the issue would be? Any help would be greatly appreciated at this point. Thank you

please define bump. A wfo on the throttle? or a blip of the throttle? or hitting a bump while riding? How was the float setting after you cleaned it up? a leaky float? (su****ion this)

congrats on the new ride for you and your son. Welcome to KF

 

as far as the bump, while its sitting on a stand running at idle, if you hit the quad and make some type of disturbance it will cause it to die, same while riding it.

 

The spark plug wire on tight? That kind of thing.....the wire ohmed out good? tight connections,,,,, I have had wires and coils do that to me before
