Re: 2001 kdx 200
Your carburetor may need a quick cleaning. But, don't dip it in carburetor cleaner.
If it runs well until a particular point, such as when the main jet assumes prime fuel mixing, it may something simple(like a dirty main).

Or, the needle may have come unclipped, isn't moving with the slide, and is blocking the needle jet.
Not that I've ever had that happen, but, all things are possible.

Re: 2001 kdx 200
Since its been sitting for 7 months I would also suspect carb. Did you drain all the fuel when you stored it? If not then definitely clean the carb.

Re: 2001 kdx 200
Did you drain the fuel tank and bowl before letting it set that long?

Re: 2001 kdx 200
power valve would not have changed
clean carb better
DO NOT dip it
How fresh is the fuel??

Black gas out of the idle speed screw? Yeah, you really need to clean the carb better. While you're at it, flush your tank out to make sure it's clean and only fresh fuel goes back in there.

Re: 2001 kdx 200
I read all the post's. I agree, re-clean the carb. Don't forget to check the Idle jet & needle & seat. Why not do the jet block gasket. Your in there so do it right.
If you lend someone $20, and never see that person again, it was probably worth it.

Re: 2001 kdx 200
No one answered your question though. Crank it up with that round power valve cover removed. As you Rev the engine you should see the valve mechanism rotate open.
Having said, I would clean the carb again. It is the most likely source of the problem from your description.
Good luck!

Re: 2001 kdx 200
Thanks doakley,i have seen people do that on youtube, if it moves it works right? but can it still rotate like half way and then only work halfway too? or does it rotate all the way or not at all?

Re: 2001 kdx 200
What if the right subvalve is missing or has stripped teeth?
What if the flapper is broken / not working?
Taking off the left cover or right cover does not show all.
You can take off the pipe to get a partial look, too.

Re: 2001 kdx 200
i see now that the PV rack doesnt move hardly at all when I rev the bike up, so anything is stuck .I have taken the governor gear off. I dont think ant teeth are gone since it worked very good when it was put away, and I see that the main flapper is down and won't go up even with me using on it..

Re: 2001 kdx 200
could be that while it was sitting the carbon build up has gummed up your PV. Give it a good cleaning.

Re: 2001 kdx 200
uppdate, it did not move almost at all. now I took off the gear on the governor obs left hand tread. started wiggling it back and forth and shot wd 40 up in the main flapper , it actually came loose! tried the bike- power is back. now the weird part reving the bike seeing in the rack hole on the stator side the rack does not nearly move like before but the bike runs MUCH better. WHY?
