Help With Swingarm!!

Hey guys I just bought a 2003 xr 70r for 100 bucks!! :cheers:But, the reason is that the rear spokes are busted on the rim and the swingarm has a lot of play in it. I took it off and it looks like the frame/swingarm bolt hole has been wallowed out. I need help figuring out what to do. Is there supposed to be a rubber gromit between the frame and the bolt? or just metal to metal? Can I cut the metal off and drill it out, then weld new ones in? also how had is it to respoke the wheel? They removed most of the spokes before I got it, but there is enough left where I can tell what the pattern is. Any help would be greatly appreciated. thanks :ride:

Do you think I can weld in solid metal over both holes, then drill them out for the right size? Here are some pics.

Wow, I hate to say it, but I thought the one I bought was bad. I thought about somehow fixing it because I don't like things not being right. If I had still been working for my last employer, I would have cut off the stubs on the frame and had a machinist make new pieces to weld on. I knew a guy who would do that kind of work (with precision) for about 50 bucks. If I were to do it by hand with a drill, I just knew it wouldn't be aligned correctly. In the end, I just decided it wasn't worth my time because the bike doesn't get used that much. It wasn't that bad after I actually measured the hole size. I just tightened the bolt a little bit more than the 29 ft-lbs that the manual recommends and hoped for the best. I figured that the extra clamping force ought to help keep it together. It's a pretty substantial force if you do the calculation. I also used some low strength Loctite to help keep the nut from backing off.

You might consider talking to a machine shop. Someone with a mill should be able bore a straight hole through if you get new stubs welded on.

One other thing to look out for is the swingarm where the shock attaches. The swingarm on the bike I bought was cracked there. I built some gussets, had my buddy MIG weld them on and touched it up with silver Krylon spray paint. If you didn't know any better, it looks like it came that way from the factory (which it should have).

Good luck. I feel your pain.

I think I am just gonna measure everything, cut them of and weld on some new ones. I cant think of any other solution. For 100 bucks I wont loose much if I screw it up.

Well, did you fix it? How did it go? Just curious how it turned out in case I ever decide to try something like that.

I havent gotten to it, I tore my acl in my right knee, had surgery yesterday. I will be out for a little while. I will let you guys see it when I am finished.

Dang. I hope you have a quick recovery. A busted bike is one thing. A busted knee ain't no fun.

Ok... I fixed it. The tabs stick out exactly 5/8" from the frame on both sides. I got steel locking nuts, and drilled them out to the perfect size. So I measured the thickness of the nut and marked the tabs, cut them off, and grinded them down. Then I put a similar, but shorter bolt through, the nuts and tightened it down with the beveled ends towards the frame so it would line up perfectly. With everything lined up I welded the nuts into place, a the way around and it looks and works great! Afterwards I primed and painted the frame with rustoleum primer and paint. It looks geat. I will post pics.





Nicely done. You went all out taking the whole thing apart and repainting the frame. Looks good.

      I have an 07 CRF70 that I have done the filter pod modificaiton by cutting the extension tube off and I have drilled a couple of holes in the end of the exaust per some instructions on a thread here at TT.
      I have recently had some problems getting the bike to idle consistently. I am wondering if I should try and rejet the bike at all or get a needle from an older carb that is adjustable. I do have a unifilter that I can put in as well with the stock pod that I cut.
      It is not that the bike wont run or start, it just seems to only idle if I turn it up significantly but as soon as I turn it down even 1/8 of a turn it dies. But the idle that I set to keep it running well is too fast as the bike will move forward if in gear and no throttle is applied.
      Any suggestions? Jetting, needle, air screw change with an older carb?

      hello guys I'm like really new to this, like extremely new but I was going to buy xr-70r from a friend and drop a Lifan 125cc engine in it (here's the link: ). Now the site says its a 4preed trans with normal gear set up (1-n-2-3-4), and manual front clutch, I'm wondering if I need to buy the clutch lever, perch, and cable then connect it all. Then secondly, what pip should I be looking for I'm not sure if the header would have to be a different style or what exactly.... please be patient with me I'm doing the best I can to learn... thanks

      Hey everyone.  Darn glad to have found this forum!
      Just bought my son a 2009 CFR70 (first bike - 8 years old) and the first thing I'm doing is scrapping the factory air box for a UNI pod filter.
      I'm looking for advice on how I can open up/modify the factory exhaust for more performance.  I heard about removing the screen and drilling some holes but have not found those posts. Any specific advice would be greatly appreciated. (Found only a couple performance aftermarket pipes that were very pricey.)
      I'm thinking after the air filter change and pipe opening the main jet size may need to be increased. It's a stock 13mm Keihin carb.  What size is recommended?  Haven't looked at the stock size yet. 
      I assume the needle is adjustable on the slide (but don't know if this would do any good or be necessary anyway) and hope there is an air mixture screw somewhere because it seems the carb could use a bit of adjustment now.  Although next to the idle screw it looks like a brass cap or plug rather than a screw. (See photo attached.)
      Thanks for any advice.  It's great to be part of this group.  Ride on!

      Hello all, reaching out to you today to get some help with a small project I am trying to do.
      I just bought a 2006 CRF50 for my 3 year old and would like to rig it up with a wireless remote kill switch for those just in case moments. I have the throttle speed screw installed and will limit it that way also but want a back up until she is proficient and I feel confident.
      Since this bike does not have electric start there is no battery. I was wondering if any one has or knows how to rig up a wireless car alarm system to work as a remote kill switch. I know I will need a 12 Volt battery on the bike which I can get. I know there is a product from 3Built that does this but the range is only 250 feet and some say it is even less than that. I was thinking of a car system since the range is usually around 1,000 feet which is overkill but I prefer overkill when it comes to this topic,
      Any DIY thoughts you might have or suggestions would be appreciated.
