    Hi @Jestus,
    You are describing the sound that the engine makes exactly! My XT is a 2014 model and it makes the same noise. (It sounds like a worn dry ball bearing when you spin it fast by hand.) When you blip the throttle while the bike is idling on the sidestand, you will hear an increase in the noise. I have found that the sound only goes away when the bike is upright or when I lean it to the right. I think that it is a bearing in the transmission making the noise, because when I engage/disengage the clutch the noise also sometimes changes.

    My solution to the problem? I only start the bike and warm it up when it is upright! Seriously though, my bike has done nearly 25 000 km (about 12 000 miles) and THE NOISE hasn't gotten any worse over time. So I have decided to ride it until something breaks so that I can find out what the cause of the noise is :-) The XT250 apparently has a good track record of reliability, so let's see if it's true. I hope my input will set your mind at ease.

    Cheers,
    bikematix.

    20190723_142749.jpg 20190723_142749.jpg I followed RL's lead and went tubeless on the rear. Originally I had planned to make the rims tubeless with structural silicon and 3M sealant tape but this was a better option for me right now. Thanks RL for pointing the right direction. Need to decide on a tire but I still have some time.

    Bikematix,

    My long time friend, Monte, answered the call. He's been in the motorcycle business for years and was one of the first merchants I met 40 years ago, when I moved here, arriving on my '76 R90. He retired and sold his shop about two years ago and now gets to enjoy his personal bikes more regularly. It took awhile to get a response as he was on a biker's camp-out with his Shovel head.

    He showed up at noon today with his stethoscope and sleuthed the mystery noise.

    Clutch basket! He surmises that when the bike is on its side stand the oil drains to the left, leaving only a small puddle of oil in which the plates spin. It's enough, apparently, because these bikes have a good track record. When the bike comes upright the oil fully bathes the plates and everything quiets down. That's also why the bike must be upright to get a proper oil level reading.

    Like you suggested. Start the bike while straddling it , or, as Monte suggested, put your ear plugs and helmet on before starting.

    I think there are few reasons why the sound has not been so prevalent before.
    -This is the first "known by me" oil change (at 644 miles), so, I had "changed something" in the equation...
    -PO stated oil had been changed after every ride (!!?..~300 miles on it when I picked it up). But he did not say not "when" that was last done, or which oil was used.
    -Older oil could have been thicker and may have contained some "break-in swarf", both of which could have changed the "cold" viscosity of the oil, which in turn, "may" have clung to the plates more(?).
    -The new oil (Yamalube Performance Semi-synthetic 10-50) was fresh and not "aged" and probably flowed better at all temps and drained from the clutch basket more readily.
    -I heard this "new noise" soon after changing the oil and also upon starting the bike from the right side, standing above the open edge of the bash plate, while in a semi-enclosed space (more sound reflection). I usually start the bike in the open, from the left side, with the open side of the bash plate facing away from me. Or, I start it while astride, with helmet and ear plugs in. All of those factors would effect the level of apparent noise from the "lightly-lubricated" clutch plates.

    Once it is upright and warmed up, there's no more "thrashing" (I erroneously referred to it as a "scraping noise", because my 68 year old brain cannot always procure the exact "idiom" required.) This accounting may have something to do with your noticing a change in the noise when engaging the clutch lever. On mine, the change is barely noticeable (minimal) when I engage the clutch, but then, I have 68 year old ears...and there are of course, many other variables, clutch wear, etc..

    Thanks for your commiseration! Between us, I think we have found the issue was "Elementary!"

    Happy riding! Maybe you could upload a photo or two of what it's like riding in and around Johannesburg?

    Which rear tire are you running? Any downsides since the switch?

    no downside , works great . Tire is a Shinko Trail Pro F255 Radial 120-90/18 . It has amazing traction at 12psi , but is somewhat scary on the street at that pressure. If you are doing much pavement I would not recommend it , compound is very soft. Shinko 700 130-80 would be a good dual purpose that is available in tubeless.

    Any details on this swap? Part#'s, cost, vendor? New to modifying the XT250, but this is first on my agenda(rear).

    The OP gave the website and part# in this thread, Webike Japan is the website. The cost was around $350 or so with shipping. I chose the cheapest shipping option by sea freight but it still got here amazingly fast. Very good experience dealing with webike.

    Thanks! Positive feedback on the vendor is reassuring.

    Had the same issue here in Texas, and it did look like rust. Soaked the tank in vinegar overnight, and it cleaned it out quite well. Then I poured in half a bottle of Marvel Mystery Oil, sloshed it around, and let it sit while I waited on Fedex to deliver the new pump/regulator from Quantum Fuel. $79.95, free shipping if you can wait I think (I couldn't--was heading for Colorado in four days so paid for next day air). Getting the old pump out can be a challenge, but can be done. It's much cheaper than the $327 for the whole assembly. Of course, now I wonder if maybe the strainer was just plugged, and the pump is OK. The Quantum Fuel kit came with three strainers. I may put one of those on, and try it. Then I have a spare...my WR250R takes the same pump.

    These are pretty good little bikes, we rode our 2013 EFI model with stock gearing, 2-UP here! IMG_1493.JPG Not saying it was easy, there was some clutch slipping going on in a few places and the EFI was running a little rich for some reason, but it made it!

    That's actually very good to know. I rode my 09 to 12,000 in Mexico a couple of years ago and it was way rich but always started right back up if I let off the throttle. (It wouldn't idle.)

    Last year I moved up to a 2013 to have FI in preparation for the CDR next Summer and I've been wondering how the FI is going to do at altitude.

    Huge kudos to your lady for riding on the back of that seat for so long! Yikes.

    Did you really have to slip the clutch a lot? More than in first gear and maybe second?

    At 22,000 km the XT decided to start squeaking again, and this time I decided to fix the damaged parts rather than just throw grease at it. The bushing and collar at the bottom of the shock have had problems since about 5,000 km, not sure why, as the other 2 bushings and collars look like they just came off the assembly line. I pulled the 3 bolts out of the lower shock linkage and pushed out the damaged bushing and collar by hand. After cleaning the bushing hole in the linkage with a round brush, I knocked in a new bushing with a socket, it fits tight, as it should. Put in 2 new end seals, loaded it all up with grease and slid the collar in, everything was moving nice, so back out to the bike, put the linkage in place, and install the 3 bolts. About 40 minutes all told, with a few breaks because I am lazy.

    Picture is taken just before putting the linkage back in the bike. Damaged parts are on the left. bushing.jpg

    Actually I did have to slip it in 1st on a couple of the steeper switchbacks, probably 3 or 4 times. If it wasn't running a little rich I may not have had to slip it. But remember I was 2-up and stock gearing, that's quite a load for that little bike. Solo should be doable without slipping because even if you are rich you could get a better run at it and rev it out a little more, gearing it down would help a lot. At the time I had trouble getting sprockets and twice they got the old XT 520 counter sprocket when I needed the newer 428 so I went with stock gearing I would suggest gearing down up there.
    I'm not sure why it was a little rich but I did haul it from 2000' to 10,000' and started riding no idling or unhooking the battery or anything like that. I hear maybe you should start and let it idle without touching the throttle when you first get there. I had other people say unhook the battery. It wasn't horribly rich but I wasn't expecting it to be rich at all. I have since brought other EFI bikes there and only one other acted the same or worse actually and I never reset or idle them when I get there.

    Recently picked up a 2008 model and started fixing it to get it registered. Main issue is the speedo/dashboard which does not work. Original costs from USD $250. How hard would it be to connect a cheap Chinese aftermarket speedometer? Ignition key is very hard to turn as well, any aftermarket locks which fit? I still have a spare one from my old XT225 which might work?

    Fun ride with my son yesterday. This was just before he dumped it and filled the air box with nice creek water. With help from my ride friends... we pulled the seat, upended the bike and then loosened the air box screws to drain.

    I’m embarrassed to say that I could not find the tool kit. Where is it on this bike. We ended up getting it running without pulling the plug... but I should know my bikes better and need to work on my tool kit. I just assumed it was under the seat or side panel.

    main question is where are y’all ordering your air filters? My usual places seem to only have the K&N and I think I’ll stick with stock. Any place that doesn’t charge $15 shipping?? I usually order other needed items from the likes of Rocky Mtn to get the free shipping. I’ll need to replace my blinkers soon as my son has been pretty rough with them and they are cracked up. Think I’m also gonna lower the gearing a bit as well as its a bit high for the stuff we ride in the Ozarks. Perhaps lower the front one tooth?
