Make sure that the jets are removed when cleaning and visually inspect them before assembly. Idle jets have very small holes and are hard to clean. Might have to use a single nylon bristle to knock out any crud stuck inside. You can also use carb cleaners in the fuel to try and clean out deposits. They are not a one shot clean, it takes a few tanks to get results.

SOURCE: 2003 WR250 F - eng. won't idle down and carb starts to overflow

Hi Jwelden,
Have you checked the float level in the float chamber?
I guess you may have to reset the float pin adjustment, its allowing more gas to pass through thn required and thus the overflow!
Not bad too, when you are working on the float assembly take the opportunity to blow out the fuel line from petcock to the carburator via the seat for the float pin,any foreign particals there would stop the float pin to seal up and thus overflow.
Fit in an inline fuel filter , this will help keep out the dirt or whatever.
Hope this helps.

SOURCE: Won't idle without choke

The pilot jet controls the air/gas fuel mix at idle . If the jet gets plugged up not enough gas gets to the emgine at idle. You will need to remove the carbs and float bowls and clean them, paying special attention to the pilot valve. Count the number of turns to remove the pilot screw and replace the same number of turns then turn counter clockwise 1/2 turn.

It sounds like your bike has been sitting in storage for an extended period of time (a year or more) - and the carburetors are plugged up. If this is the case, they will need to be completely disassembled and cleaned out.
If it hasn't been sitting (and the carbs aren't plugged up) then check that all of the normal tune-up items have been performed, especially valve adjustment, oil and filters, spark plugs, etc. If this fails to produce positive results, perform a compression check on the engine. Each cylinder must be able to produce at least 140 psi of compression in order to run and idle properly.

Sputtering at 5000 rpm


AT 5000 RPM? What is the redline on the XT 600? I had a XT 500 Do not remember my year exactly, I was thinking the redline was close to 5000 RPM and if that is the case you could be possibly hitting a REV limiter or floating the valves.
Have you adjusted or checked the Valve clearance lately along with the Timing chain tensioner to be sure all are within adjustment specs?
The example you gave where it does it in 2nd gear, 3rd gear, I am sure it would do it in any gear as it sounds exactly as if teh engine is running up against a rev limiter or mechanical limits of teh valve train.

Sounds like the carbs were not properly cleaned or set up. Choke should cause the cold start rpms to be higher than what you are experiencing. Application of choke to a warmed up engine will usually cause the engine to stall.

this sounds more like a fule problem to me, try striping the carbs out and clean all the jets out, also check the fule it reaching the carbs and its not a blocked fule tank or filter as this bike is just not getting any fule to the engine after cleaning the carbs it should run ok, but just to be on the safe side get some cleaner and tip it into the fule tank also

RPM stall at 5000/6000


Definitely carb problems. Dieaphrams need to be checked and the carbs need to be synced.

Stalling when starting


I would check that the rubber seals for the Choke circuit are in good shape and that the choke is actually working properly.

Are you sure your idle ports ( size of pinhole) in carb aren't plugged with something? What happens if it starts to die, and you give it a quick squirt of WD-40 , down throat of carb?
