    Woo, XT thread! :thumb

    I have an 05 XT with an embarrassingly small amount of miles on it. My plan is to remedy that for 07. :D My fiancé also has an XT (2002 IIRC) but will probably sell it soon as he is 6'4" and wants something a little taller.

    I haven't done any real mods to the bike, other than adding handguards, a tail rack, and 12v socket for my GPS. :rofl

    Someone asked about mileage...I get around 110 miles before having to switch to reserve, so that'd be around 50mpg. That's city mileage; my touring mileage is a bit better.

    This bike frickin' ROCKS. Dammit, now I want to go riding instead of sitting in this really boring meeting surfing the internet. Pooters. :fitz

    When I was younger I had a Honda CL70 that was a great bike for intrusion riding. The most fun I ever had on that thing was riding it to the top of a parking garage than walking it across a catwalk to the top of the county sheriffs building (department) where I spent about an hour racing it flat track style. I’ve been looking for another bike to bring back some of that magic my old Honda had and think this might do the trick.

    Great to see so many other XTers on this site! I have an 04 that I have added handguards, bigger footpegs (highly recommended), rejetted the carb and drilled the exhaust. I'd love to get a new exhaust and want to get the probillet rack for it.
    Its a great bike! At 5'5" I can stand flat footed with it, its light, fairly inexpensive to buy/repair compared to a lot of other bikes and has made a big difference for a beginner-intermediate like me! :clap
    Hope to hear from more owners!

    I finally sat on an XT at the Houston bike show this weekend and I loved it. I sat on EVERY DS there and it was a toss up between the Kawasaki 250 and the XT. It's going to be a few years before a used Kawasaki is in my price range so I think I may keep my eyes peeled for an XT at the right price. Great feeling bike, just great.

    Haaaaaargh!!! So all my complaints about jetting have been wrong. The jetting was never the problem. For some odd reason fuel is not getting to the carb. I have used about 5 different kinds of fuel line (mostly clear) once I realized that this was happening. The vent line from the fuel tank is working fine so it's not vapor lock due to that. The petcock is not blocked and as far as I can tell it's not the float needle sticking though I am going to remove and investigate it. I can remove the fuel line from the petcock and turn it to reserve and fuel comes shooting out but the minute I reattach it nada, nothing, it won't even exit the petcock under pressure and make it's way to the inlet on the carb even if the needle was sticking it should at least fill the line. I can even wiggle the fuel line and get fuel to come through. It's completely intermiten as well. This is such a simple system. It's almost acting like a vacuum operated petcock but it's not.

    Though I just did think of something hmmm. I believe the carbon can which I have removed had three lines. Two going in and one a drain coming out. If I remember correctly one of the lines was coming out of a port on the carb. Maybe the fuel delivery system is vacuum operated after all. It would be a strange setup though using vacuum from the exit side of the carb routed through the carbon can and using the tanks breather line oneway valve as a fuel stop. Worth a try though.

    I haven't done a whole lot of mods to my XT, but the best one I did was getting rid of those POS Cheng Shin stock tires. I upgraded to the Mefo Explorer MFE99 and have not had any complaints for the 1400 miles I have on them. At 1400 on the stockers, I already knew I was in trouble, as they were more than 60% worn.

    I have a 96 that I bought 3rd hand last year. I have it set up mostly for dirt riding. It is a great single track bike. Light and easy to manuver.

    Mods include MT21 tires, Moose hand guards, Ken Sean dualsport mirrors, kick starter, +5 teeth on the rear sprocket, Pro Circut exhaust and a TM33 pumper carb. I have removed everything I can think of to reduce weight.

    I thought of selling it and getting a KLX 250 but I'm not convinced the extra weight and complexity of water cooling are worth it. Heck if I want water cooling I head for the nearest stream, river or puddle. That and no kick starter.

    How is that pumper carb working for you. I've been thinking about going that route. The previous owner screwed with this bike badly and I've spent alot of time trying to unscrew what has been done. It seems that he messed with the float height and I can't seem to get it back to normal. That or the needle isn't seeling properly anyway. Still have your stock carb by chance? This one is junk:wink:

    If I end up having to futz with my carb, I think I'm just going to get a TTR225 motor, I believe it's FI.

    Hi all,
    I post over at the XT225.com board, so I shouldn't repeat myself here. Mine gets about 80mpg right now and I'm 6'3, 280#.

    Great lil' bike. Easy to maintain and reliable. IMO too cheap to waste money turning it into a dirt screamer, just go buy a YZF, Husky, whatever.

    Mine is used a lot for errands and trail riding.

    Sorry, the TTR has the exact same eng as the xt with maybe some minor timing/cam/gear differences. It is definitely not fuel injected let alone if it was, putting that eng into an xt frame would not work as you would have to modify the wiring harness drasticaly between the 2, more hassle than it's worth. The TTR also has the same carb though I'm sure the jetting is much different. I don't believe there is anything inherently wrong with the jetting as most people seem to have no issues. I just got screwed because I bought a bike with 600 miles on it that someone who had no idea what they were doing decided to mess with it. I'm going to buy a new float and float needle and that should solve my problem. I hope.

    Sweet. I cannot wait to get my girlfriends bike sorted out (ahem, you know for her sake:evil ). I missed the norcal neduro clinic and it looked like so much fun. I would love to do it on a XT. Even with the issues this bike is still so much fun. I've been browsing around for one of my own now. I better chill otherwise there won't be enough room in my garage and too much room in my bank account.

    Yay! I finaly figured it out. Stupid needle valve for the float was intermitently sticking open then shut causing a highly confusuing lean then rich then working properly then rich then lean then... A float valve stuck shut would just starve the bike for gas. Stuck open would flood it. I had suspicions but every time I checked it would be working fine. After eliminating everything else I just replaced the entire valve assembly. Viola! Runs like a peach now.

    The good thing is that while I had assumed the whole time that my jetting was the culprit (I had played around with numerous configurations) I actualy found that the bike responds really well to jetting upgrades when it was occasionaly working properly. Now that I know the jetting wasn't the problem I can go back in and continue experimenting. The top end seemed very responsive to oversized main jets and airbox exhaust mods.

    Hey, Wickerman77, I don't know if you've been following on xt225.com, but probably the next place to go before a whole lot of jetting if you're looking for power will be the Z1 mod, take off the fire arrestor, and use a hole bit to drill a 1 inch up to 1 7/8 inch hole in the deep recesses of the muffler.

    I'm planning on opening mine up on Monday following Turkey day.

    Yep already done that, uni air filter, removed the snorkel, 42.5 pilot jet, and a 130 main though I'm gonna go up a size or two on the main and reshim the needle as I had removed it during the trouble shooting. The shim seemed to help drasticly on deceleration. I had the main up to 140 at one point and it seemed to respond well with the opened airbox, filter and exhaust. I'll keep playing around till I find the best combination. I'm just happy that the cutting/bogging out issue has been dealt with. This bike is so much fun.

    Wickerman, what are the symptoms?

    If you're running wide open, and then chop the throttle shut, and it bucks and doesn't immediately and smoothly slow down, you're too rich. The small cc singles react very strongly to minor jetting and needle changes. It's not like messing with a 4-cylinder or even a v-twin's carbs. A little lost efficiency is not noticed on a 500cc+ multi-cylinder bike, but even a tiny bit lost on a 225cc single is noticed right away.

    My advice is to leave the needle stock, and get the bike running correctly at wide open throttle. Once that's done, get the bike idling correctly and starting smoothly, by adjusting the pilot screw. Out means richer, in means leaner. NOW, and only now, consider adjusting the needle. If the bike has a flat spot in the middle of the rpm range, shim the needle NO MORE THAN .020" (that's twenty thousanths). TINY changes make a huge difference.

    Charles.

    Another positive vote for the 225. My wife loves hers and I have a TT225 which I use for trail riding. Both are great bikes.
