  1. Hi guys, new to this forum, I have just purchased an 2003 Rm250 to restore. I have realised it needs a swing arm and air box replacement. My question is: What other year rm250 swing arm and air box also fits the 2003 model. Tia patrick

    Swing Arm Bearings

    Going through a 2004 CR125 I purchased and realized that I need to replace the swing-arm bearings. Says I need a press...anyone do it with just heat and tapping them out, then freezer for the new bearings and heat for the swing-arm to reinstall or am I just asking for trouble? Probably go down to Harbor Freight to pick up a 6 Ton A-Frame Bench Shop Press if needed...

    Swingarm compatibility

    Hello fellow thumpers, I got a question for y'all. So basically I am not very smart and forgot to tighten my sprocket on my 2010 crf250r. This ended terribly as my back hub is now mangled, and my swingarm is ripped apart. Also, since I didn't have my riding boots or pants on, my chain whip lashed into my leg and created a 4 inch deep gash in my Achilles. So while waiting for my leg to get sewn back together, I need to prep my bike for some ass-whooping again. What I needed to know from you guys is what year swingarms are compatible with my bike; I don't feel like buying a new swing arm because they are expensive.

    DRZ400S VS DRZ400SM

    Now that I am rebuilding my 2001 DRZ400S due to a crash.. I want to be sure that when it happens again the bike will not be completely totaled. I cannot find any axle sliders for it because it does not have hollow axles. The only thing I have been able to find are engine guards that mount to the frame so I will for sure be getting those. So I just have questions on how to get axle sliders mounted on my bike, and I also will probably be getting a handbrake sometime in the near future. Would I be better off just swapping to an SM swingarm? I wish there was a document listing all the spec differences between the SM and S models. Any help would be great. Best regards.

    Swing Arm - Grease Nipples

    Has anyone fitted grease nipples to the rear suspension component and swing arm to CRF250X? Compared with my old XR350R, is ain’t a step backwards not being able to grease the CRF.

    Yz 250 2010 swingarm question

    Hey Thumpertalk! First time posting here but been reading forums for a long time. I am looking to buy a new swingarm for my 2010 yz250 since the previous owner hadn't changed or greased the bearings since 2010 (bought it last year). All the pins in the bearings were out, making the collar grind through to the alu and make the hole where the bearing sit oval. Also he has welded the swing in one place due to a crack. Funny thing to discover huh, I just thought my suspension was a little on the hard side . So what I am asking is what swing arms will fit? As I understand it from reading alot of older threads on this forum and others 2006- yz 125/250 swingarm 2006-2008 yz 250/450 swingarm wr250f 06-13 wr450f 06-15 Would all fit, but they have diffrent part numbers for diffrent years eg 06-07 yz 125/250 and 08+ and I am wondering what that means? I think I read somewhere that it was due to change in the chain guide mount or something? Is the geometry 100% the same? Must fit with the brake and everything but I think that's fine. If anyone know 100% I would be really happy ! Thanks

    VIDEO: swingarm bearing replacement

    I have a new video out on replacing swingarm bearings on my 01 KX250. Hope it helps some of you.
  10. So i bought a 2010 husqvarna wr300 from a terrible owner, after doing a complete bottom end overhaul, was going to grease the swing arm bearings also then i discovered the bearings where in terrible condition rusted and the needles just fell right out. Honestly looked like they've never been greased. any tips on how to remove them? I've tried my bearing puller and a torch no luck and the threaded rod and socket method the lips of the bearing are broken and so small the socket keeps slipping out and couldn't get it budge. i have a press but i used it to get bearings out of SWINGARM, CUSHION RELAY it worked for one of the holes and the second hole the socket underneath i used to "catch the bearing" just straight up crushed into the aluminum housing and had to get a whole new one at least it came with all the bearing installed already... so I'm really trying to avoid messing up the swing arm using that. was thinking of using a dremel to slightly cut the bearing and pry it out anyonee have any suggestions?

    Need help with bike alignment.

    So, I just purchased a used 2014 KX250f yesterday that I found a great deal on. Guy just wanted it gone. The only problem I am running into is the swingarm/rear wheel alignment. I have the pictures right below. I know the rear fender is off to the left a little but when I compared the wheel to the seat and frame, it still looks off. To me, in person, it looks as if the swingarm or the rear wheel is shifted to the right. I don't know exactly how to tell if it is off. Is there any measurement I can take? Also, if it is off. How can I fix it? I haven't been able to ride it yet to see if I can feel it out. I live in the suburbs, and I can't get to the track until this weekend. I can take more pics from different angles if you need me too. Any help will be appreciated. Also, I got the engine mapping plugs from the guy who owned it, but he didn't have any knowledge of how to use them. I know what the white, green, and black plugs do, I just don't know where to plug one in. When I was looking over the bike, there were a lot of plugs that looked just the same. So I'm not sure which one to exchange.
  12. Hey everyone, I'm new to the forum here. I apologize if I've posted this in the wrong spot. I've been trying to remove the engine on my 1989 yz125 and have had some difficulty with the swing arm bolt. It's my first bike so I'm not too familiar with the tear down process. I've looked up some videos on how to do it and it seems like it generally requires some heavy hitting while making sure not to screw up the threads or mushroom it all together. However, my bike looks different than all the others i've seen in that it cannot be pushed through to the other side can you pull it out or what? the bolt seems to have a little play so i know its not stuck. I don't have a manual for it and have not been able to find any info online. Thanks in advance!
  13. Hey guys, my 2006 450 EXC has the very dull finish on the stock aluminum swingarm. My goal is to have it with a mirror finish. I have achieved this with all previous bikes but they have also been flat on the side. My KTM has an elevated ridge of material that runs horizontally across the midline. See figure I assume this is part of the casting process for the 1 piece mold and not geometry for structural integrity. If I'm wrong let me know. Nevertheless, if not for structural integrity, I want it gone so I can get my mirror finish. Any ideas on how to get it smooth with the outer face of the swingarm? I do have this dremel attachment that I could modify by cutting a section out to allow me to slide over the ridge and use a burr bit. See the figure to see the modification idea. This is what I will probably do unless any better ideas. Might try to ask a machine shop to do it if they have a better tool? How would they even do it? I'm not sure about mill or CNC because of its shape and being a weird shape 1 piece but not sure.
  14. I see the 701 manual shows engine maintenance done with the engine on a stand. How can I take the clutch cover off without removing the right footpeg/frame bracket which will mess with the swingarm pivot??? There's nothing in the manual and I don't want to cause an issue with the swingarm if I can find a work-around. ONE cover bolt is behind the footpeg! What a pain! Thanks!
  15. My son's CRF 100 needed linkage and swing arm rebuild. I bought the Pivot Works kits that replaces the OEM plastic bushings with steel needle bearings, seals, and roller pins. The needle bearings are super tricky to install. The needles are in open races with no retainers, and want to just fall out. For the linkage I used the dust caps as guides and just pressed them in. I Still had a few needles fall out but wasn't a huge problem. The swing arm is really hard. The kit comes with 2 bearings to replace each plastic bushing. I've heated the swing arm and froze the bearing but still having a hell of a time getting them pressed in. Question 1. What are the tricks to getting these bearings pressed into the swingarm? Question 2. Why are there 4 bearing seals instead of just 2? Question 3. I think it might have been better to just buy new plastic bushings?
  16. I have read quite a bit on here about anodizing and cant really seem to come to an understanding of it. I have a 2000 kx 125 I'm currently completely rebuilding. I just scored a new swing arm off eBay because the current one is trashed. I plan to get my frame powder coated black because it's steel. I want to get the swing arm hard anodized black. There are no anodizing shops near me where I live. I called one that does anodizing in Green Bay Wisconsin and they said they woukd be happy to do it if I send it in. They asked me if it's aluminum and told me that is has to be sand blasted and completely stripped of any steel. I have read on here that sometimes if the aluminum is cast it messes up the anodizing process. So my question is, is a stock 2000 kx 125 swing arm cast aluminum? Can you anodized cast aluminum? Other than the chain tension bolts is any other part of the swing arm steel? Will this &%$#@! me and I'll lose 100 bucks on the swing arm I just bought? Please let me know if you have any experience with this stuff.
