    Spooning on a tire is like wrestling an alligator: It takes some strength, some attitude, has the potential to get bloody, and it has to start (and end) with beer. :wink: :slurp

    The two things you have to get right are 1) you MUST get the opposing side of the tire/bead into the center of the rim (as far in there as you can....otherwise, you will never get that last 1/4 on), and 2) you MUST lube the shit out of the bead or you will likely tear it (AMHIK :shog ). There is a 2.5 thing also, but it's only a huge help vs. a MUST, and that's to have decent tire irons. I've always used the 15" curved ones and they make the job soooooo much easier.

    I change my own street bike (tubeless) tires also, which are arguably much harder, and have little problem using those irons (3 of them). Highly recommended. :thumb

    I seemed to have snapped off, while removing, one of the two bolts that hold the seat on from underneath. Not sure how or why it happened, but it did. Of course, it snapped off flush with the captive nut...so I can not even try to use a pair of plyers to twist it out. I am gonna try to drill and retap.

    Worse case, I can yank that one(captive nut) out of there and replace with a modified T slot nut from McMaster.

    I looked on the fiche, and it does not seem that the nut by itself is available from Yamaha.

    Anyone ever have any issues with these??

    For right now, the seat is fine being held on with just one.

    These work. I have used them many times to recover from ham-fisted so-called mechanics.

    A small left hand drill bit will probably catch it and screw it out!

    I love this tire iron. It is much easier to reach around the tire bead and grab the rim with these irons. I have some of the 8" straight ones and the 15" makes it so much easier. I can usually do it with only two irons; a long one and a short on to hold where I first started the bead.

    Keep us posted on what you find out -- my '08 is making a similar noise. I can't quite pinpoint it, but it's a high pitched squeal coming from somewhere in the lower end. If I give it a touch of throttle to increase the idle, it quiets down. Does yours do that? Been doing it for the last 500mi or so, I have right around 2,800mi on it, doesn't seem to get any worse, oil change didn't have any impact.

    In the shop (cluttered garage) I use some fancy tire spoons and a monster bar I got from Harbor Freight.

    I also use the HF bead breaker

    On my KLR, I just carried the fancy spoons and used the kick stand to break the bead.

    Yes, its excellent advice to use the stuff on your bike to change the tires, and I did that the first time. However, its much easier (less frustrating) to change your tires using shop equipment.

    In fact, I'm thinking of get the little No Mar changer just to save myself the time when I change out my GS's tires. Currently I take them to Cycle Gear and pay $30 per wheel for mount and balance. It would be quicker for me to do it in my garage than mess with Cycle Gear.

    I think mine does quiet down when I engage the clutch and pull away from a light but it's hard to tell. I always wear earplugs and the WR is such a loud bike even bone stock. Not just exhaust but lots of mechanical noise as well.
    The squealing is so loud it gets on my nerves sometimes at lights and I have earplugs in.
    I am just going to ride it another 2k miles and until the next oil change and then send in the oil to get analyzed at a lab to tell me if a bearing is going. Let me know it anything happens to yours in the meantime.

    I'm not sure if it's the same issue, but contact little squirt on the wr250rforum because he had some sort of squealing noise that sounds very similar to yours. I think he initially thought it was a crank bearing but it turned out to be something else. But I think it's worth a shot to ask him.

    Just FYI thats a WR250F not an R....to bad it was not closer to me, would be a nice enduro riding bike.

    I went through that post and listened to the noise. My NX250 used to make that noise. I think it is gear noise. Not really a problem just a feature.
    All bikes make some strange noises.

    Thanks for the heads up. I'm on the same island as him so I'll see if he can check it out.

    EDIT: looks like he never found out what the noise was from. He ended up selling his bike.

    Absolutely.

    You guys are making this sound scary. I've changed dozens of tires without ever resorting to knees or feet.

    For street tires, if anyone is thinking about the Nomar tire changer, you might also want to consider Cycle Hill. It's also made by Nomar but is less expensive and works well.

    On the '08s the squeal is most likely coming from the stupid rubber damper they put on the sprockets. Mine started to make noise so I cut the rubber off(took some time). No more squeal. New sprockets would work too. but I'm cheap and the originals were still good.

    Both of my sprockets are aftermarket, so that's not it.

    That's definitely my noise. Saw Keith bumped the thread -- I'll be watching it.

    Does anybody have a stock seat for a WR250R that they would like to sell me? I'm looking for one of the blue/black ones in good condition.

    I know a lot of people have switched seats and might have the old one sitting in their garage. PM me if you have one available. Thanks.
