It is a fuel screw. It is very sensitive and turning it in a quarter turn can be enough to lean it up just enough to run smooth. A couple months ago I went through the same drama, cleaned the carb and found all it needed was a slight adjustment.

Actually, If you haven't bought a jet yet here's a good place to get one (and many other carb parts as well.):

Selling my trusty XT. Makes me a bit sad, but I realized that I've spent more time putting it away each fall and getting it out again each spring the last two years than riding it.

I have a 2001 XT225 and feel like my front fork sags too much.
Are the front forks air sprung, use a coil spring or both?
If air sprung where would I find the valve to check the pressure and add air if necessary?
Cheers

Coil spring. Some of the older ones had schrader valves on top of the fork but i believe air pressure wouldn't raise the front end regardless, they were there to tune the "bottoming out" characteristics of the fork. You can make preload spacers and add them to your forks to adjust sag.

Thanks for your help Alonzo. I never understood the difference between diameter and area.

Given your experience, I may skip shimming the needle.

It's a shame you can't get the pumper carb kit for this bike any more.
After redrilling the muffler I had a little high speed stumble. I then replaced the air filter with a Unifilter, and now it runs perfectly.

Formula: remove snorkle, rejet main to 130, drill muffler, add unifilter. A shop already turned the pilot screw out. I don't really like the noise, but the performance is there. 800 feet above sea level.

How to pack up an XT225 for cheap







Already had most of it, just had to buy about $20 worth of bits and pieces to put it all together.






Not worth the climb.

I have a Z1 modded pipe. It was done by the PO of one of the three XT225s I have. I left the snorkel in, and use a stock filter. Here in the AZ dust, you need all the protection you can get. I also have it jetted just a little rich, to help keep it cool in the 110+ temps here. Plenty of power for a trail bike, even with my 230 pounds on it.
