Could be bad gas, or clogged up carb. Try a small dose of "heet" then a good shot of SeaFoam. The Heet will help absorb any water in the gas, then the SeaFoam will help unclog carb. The Seafoam will not be immediate, I have heard instances that it took numerous SeaFoam treatment. Good luck

A simple fix would be to turn the idle screw up a little on the outside of the carb. My bike has about 2000 miles on it. When I was riding with some experienced guys last fall, one did that and it never stalled again after warm up.

I have tried several times adjusting the idle screw on the side of the carb- May play with it some more- weird thing is that several times I have and even a miniscule adjustment will send the idle WAY too high. Where is the idle mixture screw hidden on this thing?

Don't think it's bad gas, I have filled my KLR from the same hose each time the DR has been filled. I may throw a bit of heet and or seafoam in the tank though- Thanks

Messing with the idle simply covers up the symptoms of the problem.

The idle mixture screw is under a brass plug near the front of the carb. You'll have to pull the carb, drill out the plug, and carefully remove it.

Thanks tbolt- Is there a baseline for how many turns out/in to go with it?

My bike had this exact symptom - in my case it was the o-ring on the needle valve assembly causing the problem.

I am currently having the same problem and turning the idle screw up on it really is only getting me by until I get home and can have someone look at it. It isn't stalling now but I have to play with the clutch so it doesn't over rev when idling. It's really annoying. Plus, it is now sputtering when I am riding steady around 40 mph. I hope I don't need a new carb and am hoping someone can rebuild mine but I am sure the carb is the problem in my case. Interesting so many have this issue.

All of the past several posts are indicative of plugged jets or leaking needle seat o-rings. When the slow speed circuit is overlean, the idle will want to run away or not idle at all, and when the mid range and main circuit is lean that will cause missing, hesitation and backfiring.

Time to clean those carbys. Remember that the little DR has small jets and passages and even though it may look clean it likely isn't.

After you remove the plug, turn the mixture screw in until it stops and remember how many turns it was.

Thanks for this! I will learn to clean a carb when I get home from this trip. I have my bike running but it sure wants to rev up if I don't control it with the clutch when I am idling. I really hope a good cleaning does the trick because I don't want to spend $300 on a new carb like I was told I need to do here.

The DRZ has a smaller headlight than the 200 so you have to enlarge the headlight opening the DRZ cover. I think the blinkers had to be relocated too, can't remember for sure.

what did you use to enlarge the headlight cover? a sander?

Thanks guys- I will have to pull the carb and clean it and check the mixture screw. Geez, and here I thought this thing would be less trouble than a KLR.

You have a KLR bored out to 685 and you're complaining about drilling out a mixture screw plug?

My wife crunched the numbers recently, and after about 14,000 miles on each bike and ten years time, our two DR200s have paid for themselves in saved fuel and other costs. All further mileage will be pure profit and fun. Great way to look at it.
