Stumble at Idle

Recommended Posts

Hi guys,

I have an 05' KLX 300 that stumbles at idle. It didn't run for about three months due to moving etc. I drained the gas etc. but no luck. The old fuel had Stabil in it. It runs fine other than the rough idle. I'm not a carb guy so where should I start?

Oh, Four Strokes re-worked the carb when I first got it (new jets etc.).

Thanks

You need to clean out the pilot jet and any associated passages. The pilot jet hole is literally not much bigger than a hair and clogs easily. Get some carb spray and pull the carb and clean the whole thing out and you should be good to go. Be careful as you pull things apart so parts don't go flying or get lost.

The only thing that I would know to tell you is to change the gasoline in the tank. the gas is really bad. keep it out of the carb to. make sure that you keep the tank full.
