  1. So my yz 125 is in need of new swing arm bearings but a new bearing kit it quite pricey. I am able to get the bearing itself for cheap so would It be okay to jsut put new bearings in and run the same collar? And is it bad to ride the bike with bar swing arm bearings
  2. Hi I bought a 2002 yz250 with an aluminum frame . Great bike . Time to redo the bearings . I was told by p o that everything came off a 2002 except frame . Just note sure if that is correct . Will a 2002 swingarm work on a aluminum frame ? Can I measre some bolt diameters ? thanks .
  3. Hey, Today I decided to off the swing arm to install new swing arm bearings (noticed that the previous owner hadnt regreased the linkage bearings so was quite convinced the swing arm bearings would be in awful condition aswell.) So the bearings had completely fallen apart and rusted. Now I cant seem to remove the last layer of old rusted bearing from the swing arm hole. (see pics) Anyone have any suggestions for this part? I've tried soaking with anti seize, hammering, pressing of all sorts. Its completely stuck and rock hard. Most parts like rusted O-rings and other seals I were able to get out with a hamer and a screw driver. I suspect there is one more layer that needs to be cleared out, am I right? Thanks in advance, John
  4. Hello posting again about my 93 Kawasaki kx250 After disasembling the frame and suspension components to replace them, I was left with both outer races of the swingarm bearings still stuck in the swingarm. All the rest of the pieces of the bearing fell out when i pulled out the long bolt that held it to the frame. The issue is i cant seem to seperate the bearing races from the swingarm. Ive tried heat, pounding it out, using a impact socket of very similar diameter as the races to pound out and nothing has worked. Any suggestions?
  5. So i just had my swing arm bearings replaced and I try putting the swing arm back on my 2017 kx100 and like an idiot I forgot to put put the bolt through these metal spacers you could call them. They attach to the frame and go on each side of the engine. I forgot to put that on when tightening the swing arm to the frame and there was space between the frame and swingarm. I tightened the swing arm axle and it bent the right part of the frame where the nut is for the axle. It bent it in so now the swing arm won’t fit with the metal spacer things. Now I’m kinda screws because I don’t know what to do about bending the frame back. I don’t have to bend iT back much but enough so the swing arm fits. Any help would be very helpful. Thanks!
  6. Hi everyone, New to posting here and thanks in advance for any help. I have a 2003 Honda CR250 and am in need of a swingarm. I know that some people have used swingarms from a 2005 CRF250 with good luck. Unfortunately the ones I have i have been finding for both bikes are either roached or way to expensive for my budget. I have seen some decent ones for 2004 ,2006,2007 CRF250 that don't seem as bad, but the part numbers seem to change almost every year and don't want to order the wrong part.. Any help on other fitment options or anybody have one in descent shape for sale would be greatly appreciated !! Thank u, Jason
  7. I recently performed a nut-and-bolt rebuild / restoration on a 2004 KLX400R - or a Green DRZ - for those that haven't seen one. It only had 3000 original miles on the clock...but one thing quickly lead to another. and the bike was in a million bits. Lucky I am retired I guess. Frame blasted & 2-packed. Wheels respoked using stainless spokes. Everything detailed or soda blasted Registered and on the road....these are mostly the old plastics but I have a complete brand new set with replica graphics set put aside. Brand new Staintune exhaust The maiden voyage was to be the outback so I also have a 16L Acerbis tank, case savers and luggage racks all ready to go. Other than the exhaust much of the stuff is used refurbished, just to keep the budget in check. I only put 300km (less than 200 miles) on the bike for testing and setup purposes. Needless to say I was pretty unprepared and the bike handled like a sack of s**t. The front wheel felt like it was on marbles any time the sand or gravel was of a certain type or buildup. In 45 years of motorbike riding I have never felt so slow and over cautious! Lucky for me I was travelling in good company with seasoned racebike builders, helicopter and airplane engineers, so we spent a good deal of time around the campfire trying to sort through my handling issues. We tried & checked a myriad of things but to get the wheels to track inline required the RHS snail cam to be 2 clicks more than the LHS. After we got back I turned up a set of equal length shafts with pointers on the end, convinced that I had spent all my efforts on a bent frame. Each one of these shafts was set through the center of the hollow pivot points (incl. headstock, front axle) , allowing a tape measure to be used with some degree of certainty. The results were all within +/- 1mm (0.040") meaning that the frame and swingarm should be straight enough for a dirt bike. Note: My measuring ability tolerance would be only in the vicinity of +/- 1mm (0.040") anyway. (The concrete can't be used as a reference surface as it can be up to 3mm out!). What I did find though is that the front wheel was offset 8mm (5/16") to the right from the bike centerline. Oh crap... my front end must be bent because the rim is still central between the forks. My friend bought his 2015 DRZ over and we measured up his bike. Using the stringline method his offset error was less than a millimeter whereas mine was still around 8mm or so. After taking off his front guard we found that the frame front downtube was also offset to the bike centerline, just like mine. The rim offsets were the same - central on both bikes measured off the discs. The tell tale was that his rear tyre was more central between the swingarm than mine so we measured up swingarm offsets. Mine was 18.5mm and his was 9.5mm. Oh crap...now the swingarm is bent. Lucky I have some leftovers from my parts bike...ex-army Special Forces Suzuki. Lets measure that one up... Hmmm...what would be the chances of having a 2004 Kawasaki & a 2005 Suzuki swingarm being bent within 1 mm of each other? If only I measured the sprocket alignment in the beginning. They are both out by 7.5mm - further evidence that the swingarm is bent or offset. BTW, the sprockets still wear pretty good considering they are so far out! The factory wouldn't have sorted out this problem would they? The part number is the same for the swingarm from 2000 up until 2019. I have searched & searched and found nothing to indicate that there was a batch of bad swingarms built. An opportunity arose to get a brand new swingarm, removed from a bike in 2007, cheaper than the price of a set of bearings, so I got it. Well bugger me, this swingarm measures identical to the 2004 & 2005 units. So after all of this epic-Corona-virus-tale....my questions are: Q1. What year did Suzuki fix the swingarm alignment issue? All I know now is that it is after 2007 but before 2015. Q2. Is this common knowledge or have people been under the illusion that their bike has been accident damaged when it possibly hasn't at all? It's OK to tell me if I am crazy.
  8. I am going to replace swingarm bearing but the shaft is stuck. I have read all the threads and seen the home made pullers. But i have a extra swing arm shaft and nut. So can i just go to it with a hammer on the shaft? Any problems with this idea? Any big problems if i bend the end over a little or mushroom it a little?
  9. Well after 2 years of fighting with my 125 build im at a stalemate. Aside from the frame the entire bike is new. Went to put new swing arm bearings in it and found out the chain ate the bearing cast material to pieces. Had it welded and after hours of dremel work got the bearing in. But the two bearings arent true and the motor mount/swing arm mount bolt will not go through (must be bent ears). After a year of searching for a swing arm I'm going rogue and looking for a parts bike. My question is, is there a chassis similar enough to the 03 kx125 to bolt in rear swing arm/suspension? People want crazy money for 125 chassis with blown motors. Looking at a few kx250fs that has similar swing arm geometry (05) but didnt know if the front of the swing arm has the same specs size wise. But i know yz and rmz chassis are similar. I cant justify spending 6-700$ on a new one. I called a few shops and they just tell me they cant help me. Ive looked up some specs but dont have access to the bikes in question physically otherwise I'd just measure it myself. Any help would be appreciated. Way too much money sitting in the garage. I need to ride this pig next year. Picture is a little old but doesnt look too much different.
  10. I have a 07 kx250 2stroke. I acquired it in pretty bad shape.i can not find a replacment swingarm so I am going to try and fit a swing arm from a later model kawasaki 4 stroke. I also believe If i can make this fit it will help with the horrible frame geometry. If i get a new swingarm the linkage should drop the rear end 1.5 inch and give me 1° of rake angle for the front. Helping diminish the pogostick rear end and hopfully geta front end that can stick to the dirt. Can anyone give me some measurements for where your kawasaki swingarm meets the frame and engine. Also the measurement for the linkage connection. I havent bought the swingarm yet so any 1 that wants to take some measurements can you please give the year and the bike you are measuring... preferably 07-12 kx250f
  11. I was removing the rear swing arm on a 2007 crf450r when this washer fell out and I didnt get to see where it came from... if anyone knows the proper location of this washer it would be much appreciated
  12. DRZ 400 Swingarm Pivot Bolt Removal Tool In Aug 2018 I bought a 2016 DRZ400S which had very low mileage. In the fall I decided to pull the Pivot Bolt for the swingarm, just on spec….yep it was corroded, but saveable. I used the concept from “2 Wheels” that was posted in the FAQ area, and adapted it to make it more effective. His concept used a section of pipe, washers, nuts, and a 3 foot section of threaded rod. As is indicated in the FAQ article, the limits of this puller is the strength of the threads on the rod, as once you reach the limit, if the bolt has not moved, further tightening simply strips the threads. His technique then involved hammering on the other end of the rod, which is a challenge to do without damaging things. I adapted his idea as follows: - using the same rod, - locking two or three nuts on the chaser end that will follow the bolt as it is pulled, and rounding them on a grinder to a size slightly smaller than the pivot bolt - taking the 3 pound slide weight off my slide hammer and putting it on the other side - using multiple washers and 4 nuts locked together on the end of the rod. The technique: pull the rod through the pivot bolt until the chaser nuts are solidly in contact with the threaded end of the pivot bolt, then slide the 3lb weight on, then multiple fender washers, then 4 nuts. I then started a series of blows with the 3 pound slide weight against the washers/nuts on the end of the threaded rod, to pull the bolt. This allowed for significant impact force to be imported on the pivot bolt with no issue of missing/damaging things, and it completely avoided the stripping the threads issue as the nuts are not turned and are locked in a combo of 4 together to spread the force. My clever plan, if the normal grade threaded rod could not hold the stress was to get a rod with a much higher SAE rating and do it again…but I was fortunate and the stock rod was enough for me. Here is the image of the “chaser” end, which is two nuts locked together and ground down on the grinder to a diameter just smaller than the pivot bolt. And here are a couple of images of the slide hammer or puller side: And Finally, here is my pivot bolt after one very short season and no real mileage!!!!
  13. I just had my 2017 kx100 swing arm bearings replaced by a shop and I get it back and I try installing it and I can’t. On the right side of the swing arm hole near the clutch cover, there is a dust cap that gets in the way. It like sticks out very little. I’ve tried fiddling and playing with it for hours and it won’t fit. Idk what’s wrong so some help would be great! Thanks!
  14. Bought a used 2007 rm250. I was working on replacing the chain and I can't get the axle/wheel correctly aligned straight. On the right side of the axle where the knut tightens, there is no block like there is on the opposite side where the chain tightening/alignment bolt pushes against it to put tension on the chain. Oem part diagrams don't show one, and I can't figure out how the axle is supposed to stay straight because right now it is loose. Can someone please help?
  15. Hi, I might be dumb, but I have a 99 xr80 that needs a lift now I've heard of the Aussie lift but I don't have access to a welder would extending the rear swingarm linkage do the job? Any help would be appreciated, thanks!
