Engine only idles with choke on (Problem FIXED)

Recommended Posts

I thought I would post this for new riders, since many OP's never follow up post what fixed their problem.


I have a 2008 Kawasaki KX250F with a carb (not fuel injected). The bike would only idle with the choke on. When I turned the choke off, the bike would pop, backfire and stall.


I installed a new pilot jet (42) for $6 in the carb. I didnt have to remove the carb, I just accessed the pilot jet by loosening the carb and removing the nut underneath. There are plenty of YouTube videos on how to do this.


The repair took 10 minutes and it purrs like a kitten now. I'm new to this, so anyone can do this repair.
