    Yes, thanks for the info. That's something I may look into. For anyone else that may be interested, here is the info on the swap:

    Lisa, I had a 1992 XT225 for many years and many, many miles. A great, super-dependable bike but I started worrying about the miles I had on it. It was either do a complete rebuild or find one with fewer miles. As luck would have it, shortly thereafter I found a 2007 with only 247 miles on the odometer and sold the 1992. Now, I live at 4400 feet in elevation and most of my riding starts there and goes up to around 12,000 feet - so I was surprised to find how lean the 2007 ran, even at those altitudes. If whoever owned that bike before you did has not done it yet, you might want to read up on what it takes (pretty simple fix, really) to rejet the carburetor and have it run like it should. Lots of good information on this site and over on XT225.com.

    LisaS, inquiring minds want a closer look at that front wheel. :evil

    OK, I know I have asked similar/same Q in past but given your experience above I am going to be bold and ask anyway. What jet size(s) did you use and did you do any intake or exhaust mods? Did you do the pilot screw adjustment or shim the jet needle also? Opinions on these are all over the place, some earlier posts in this thread indicate the bike becomes un-rideable with even only pilot jet up one size to 42.5. Other posts indicate that larger jet(s) prevent proper atomization of fuel, some even used smaller than stock main jets when opening the intake and exhaust flow (that one certainly doesn’t make any sense). I plan on working on the carb today or tomorrow and for sure will do the pilot screw adjustment but keep going back and forth about jet changes. I bought one size larger main and pilot jets for an ‘06 and the bike will be ridden from essentially sea level to maybe 6,000 to 8,000 elevations so I would greatly value your opinion. I don’t plan on doing the exhaust or snorkel mods or drilling the air box. At most I will change the filter element to a unifilter but I doubt that that makes much difference compared to stock.

    I would start out just doing the 3 turn out on the fuel screw. If you are not going to open the exhaust or modify the snorkel, the stock jetting may be OK. I have the 3 turn out, Z1 exhaust mod, UNI filter, 42.5 pilot and 130 main. Snorkel has the bottom section cut off and I added (2) 1" UNI filter plugs to the side of the airbox. Runs perfect at our 1200' altitude.

    As I said, do one thing at a time.

    Hey CamperBob. Went out in the shop and looked at the front tire of Lisa's new xt. Looks like a stock rim with a worn out tire to me. The new parts are starting to roll in. New jets, tires, fenders, bars, handguards, tail light, turn signals, pegs are a few of the mods.

    Musta been an optical illusion. The tread pattern looked like maybe some kind of studs or chains or somesuch for riding on that white frozen stuff featured so prominently in the pic.

    Took the XT out for about a 70 mile loop on back roads in Litchfield Cty CT. About 30deg F., but thanks to Mr.gerbings, very manageable. Just had to remember to pull the plug about 5 miles before I stopped to recharge the battery.

    Great to be out, and the XT was running wonderfully. I think it loves the cold weather. :lol3

    After reading several posts regarding carb mods over on XT225.com, I went with a 42.5 pilot and 130 main. One washer shim under the needle jet, and 2.5 turns out on the pilot screw worked best on my bike. These mods made all the difference in the world to my bike - it runs cooler and doesn't backfire nearly as much when I back off the throttle. Runs great at all altitudes and in all rpm ranges. it might be my imagination but now when I use my 16t countershaft sprocket it seems like I can hold 6th gear longer going up hills.

    Thanks! Is the rest of your bike stock or did you change/open up the intake and/or exhaust? I don't want a louder bike so I don't plan on changes to the snorkel/intake or exhaust.

    Intake and exhaust completely stock. The older I get the more I can't stand noise. Quiet as the XT225 is, in the last couple years I pretty much always use foam earplugs when riding (and that's even with a Bell helmet that clamps tightly around my ears).

    What is the charging output of an 01 225. I have gerbing gear that I use on my other bike that I didn't think it would work on the little bike. I see someone else here used it on the 225 and was curious what I could get away with.

    I ran yesterday with a Gerbing microwire jacket liner, and an older pair of their gloves. I was sufficiently warm, and based on past experience, pulled the plug about 5 miles before I stopped to allow enough time for the battery to recharge itself. It restarted on the button fine. In the past, I've had dead batteries if I stay plugged in until I stop. I installed a kick starter for that reason. The bike will start with a dead battery and run fine. Run and bump works too.

    My current battery is new this season, and I figured I'd experiment. As I was approaching home yesterday I decided not to unplug. When I reached home, I turned it off, and then hit the start button. It turned over and started, but just barely. At that point I plugged it into a charger.

    first of all, thanks to speedo66 for the gerbings info. now for the age-old question of jetting... i bought a 130, 135, and 140 main jet that i plan on experimenting with. i don't mind modifying the snorkel but i do not want to modify the exhaust. so if someone has a suggestion as to what would work best with just snorkel removed.....let me know.. i saw comments on shimming the needle jet. i am familiar with shimming the needle but never heard of shimming the jet..so am i misinterpretting the way it was written or are we talking about shimming the needle? point me the right direction............thanks...

    I recently messed around with the snorkel, thankfully I had a few snorkels laying around and could experiment with. Power was best with the snorkel completely removed but it was loud. Second best was with the section inside the air box removed and the top part installed backwards. Added a little intake noise but not much and with the helmet on I could hardly tell the difference. Pretty much any mod of the snorkel will add some sound so if you are completely against added noise you are best to leave it as is.

    I'm not an XT dude, I'm a TW guy but we're saddled with the same crappy 110mm rear brake. I'm doing a 130mm rear brake conversion on a TW200. Don't stone me, but since there doesn't seem to be a TTR thread and a few of you may own both or have converted your XT to a TTR rear drum, I need a pic of a TTR rear brake backing plate.

    More specifically I need an edge pic of the swingarm tab slot in the backing plate. Here's the TW:

    [​IMG]

    And here's one from an XT350, which is one of the few that shares the same brake shoe diameter and axle hole size. The bottom of the slot is too far out from the drum. The TTR is a candidate and I'm hoping its slot depth is at least somewhere between the two. If anyone can help me out with this I'd sure appreciate it:
