Question for a friend...Gray im sure you know.

Any YZ450F carb specialists out there?

Have a situation where the bike occasional has a high idle but it is not an air leak. Buddy of mine says it is probably the rocker arm that controls the slide that is worn. Just looked a the parts diagram of the carb but don't see it listed.

Anyone have a part number please?

Im not sure year yet he hasnt gotten back to me

I'm assuming you have tried richening the pilot circuit a little. Have you made sure the hotstart is closing all the way?

Both good suggestions. Also, be sure to look at the valve clearances. Tight intakes can cause this.

mine does this right now because the re-positioned hot start has a little drag in it. its just to low on my list of fixes. It may do it once a day
