00 wr 400 idle

6 posts in this topic

Just picked up my new W.R. on 2/5. On cold starting it seems to have an unusally high rpm idle with choke on. Anyone else experience this?

My 99 is doing the same thing. It idles very high with choke on and when I turn the choke off it will die shortly after. I have yet to find a common ground. It just started doing this a couple of months ago.

Hey guys,

I am not an expert, but it sounds like there may be something sticking in the carb. Maybe there is some dirt, OR, the dreaded cracked slide... AGGGGGHHHHHHH :)

Isn't the increase in rpm due to the enriched fuel mixture with the choke on? I have seen several other types of 4-strokes do this, also. Nothing was wrong with them or their carburetion. I personally wouldn't worry about it. As for it stalling when you turn off the choke, isn't that because the motor isn't warmed up completely?
