    I'm unable to locate a thread that fits the XR200R. I just bought it a few days ago, plated it and have laid down a few hundred miles on it. It's a 1986 model that I bought off the original owner. He said it got more scratches sitting in a shed than it ever did riding. I'll be a day or two behind on pictures due to a failed camera.

    Questions/Problems...

    1.It only runs out full throttle with the choke lever in the half up position. I'm guessing the carb needs a rebuild due to a plugged jet. The PO had the carb cleaned at the dealer and added Stabil last year(which was the last time it ran)

    2.The rear wheel has a slight wobble at speed which I'm thinking is the bearings.Has anyone replaced these bearings? Are there any special tools required?

    3.There is no brake light. I'm told it's a 12 volt bike, but I don't know if the stock electrics can handle another light. I don't want to spend the cash on a "kit"

    4. Does anyone know where all the good farkles can be had. I would love a rack on the back to hold a milk crate for bringing home the "milk" and may just have to build one.

    So does anyone else have/ride one of these bitchin' dirt scooters?
    Please post up:clap

    You really need to go and clean out the inside of the carb. Because it's so small and has extra-tiny passages they clog quickly when the bike sits. Don't clean the jets, replace them. It's worth the $8.

    If it's the bearings, you'll be able to shake the wheel from side to side when the bike is at rest. Another thing to try is start the bike and stand next to it on the kickstand side. Shift into second and pivot the rear wheel off the ground and let the clutch out. Give it some gas. You'll notice the rear wheel shift fore and aft if the bearings are bad. You'll also be able to tell if it's the spokes/rim that's out of true.

    The 1986 XR200R came with a factory headlight and tail light which is the same for all the XRs that came with lights that year. It is 12v. Look on eBay for lenses, bulbs, housings, and plastics. Cheap! The tail light is a 5w bulb, the headlight is a 35w (don't quote me on that) and the stator puts out 35w (don't quote me on that either, but it's close to that)

    Check around on eBay. I'm not sure if anywhere still makes racks for it but there's some good deals floating around.

    I had grand plans to build up a full-race XR200 (218) engine but came to my senses when I priced the build. I do have an ATC200X big fin barrel on mine.

    A few years ago I got my wife a cherry 2002 XR200R and tossed the stock suspension for a 1990 fork and 1984 shock which is the same setup as your 1986. It was a fun little trailbike. Now I have a 1980 XR200 motor in a 1995 CR500 frame and swinger with a 1999 XR600 fork. It is yet to run and a fun project.

    A hydraulic brake light switch that screws into the top of your rear master cylinder is ~$20 or less. Put a dual filament 1157 bulb (some XR's come with them already) and do a search for the third wire (how to connect, it's easy - goes to the other "foot" on the bulb base)

    *edit* wait....this is an XR200, so rear drum brake... get the mechanical switch for even less

    rear isnt hydraulic. drum brakes. Front too. You will need a pull switch with a spring. Procycle has em. HAve to have a different tailight as the stock one is a running light. Not alot of power from the stator so the lights will dim at idle.

    Bearings are cheap and easy to change. Heat gun and a good beer.

    I rebuilt one of these that I got in a couple of boxes. Motor and frame. I spent about $200 for piston and valves that I put in myself plus full gasket kick as the motor was toast. These guys are low compression tractor motors. Good fun. Keep an extra front brake cable zip tied to the one that is hooked up. That will get you out of the woods. Clutch cable too. Carb clean is a must. I usually just replace the pilot jet ($3) when I do one.

    Exactly what I said in the post above, edited within seconds of posting a couple of hours earlier....and almost any bike shop will have them back by the $15 Acerbis mirrors and hydraulic brake light switches and dualsport stuff

    Baja Designs' dualsport kits come with them as well as the hydraulic switch - so if you know someone who has installed the kit, he's probably got the mechanical switch left over.

    You guys rock! Thanks for all the replies. I'll get some pics later. I wonder if I should find some low watt LED to replace the rear running light so that I might have egnough power left to run a brakelight.Two wires heading back to the running light means I could tap into the positive, run it down to a mechanical switch and then on to a LED taillight. I'll pick up jets at the Honda dealer(I hope they have them). Thanks again guys:D

    Your stator is putting AC power to your headlight and 1156/1157 rear bulb.
    LED's need DC, so you could do that if you had a dualsport kit with voltage rectifier.

    I run an LED taillight bulb on my XR, but that's because rough offroad riding has killed it's share of 1157's. (I have a kit with AC and DC output)

    Well, this is a handy thread to roll around.
    I just started working on my friends '90 XR200R. It doesn't want to start or stay running if it does start.
    Seems to have a weak spark. I've read that is pretty common on these bikes. Is that true?
    One thing that is weird is that if you remove the stator cover, there is always some oil in there. Is that normal for this bike? once you cleam the oil out, it seems to start better. Could it be related, or is that unlikely.
    I suppose we could just be wiggling a loose wire when we mess with the cover and that makes it work better.

    Hmmmm.
    They could have made that much shorter by saying...
    "Anything"

    What about the oil in the stator cover? Normal?
    I really only have experience with my XT, and it has main seal to keep the oil out of there. Looking at the parts breakdown, it doesn't look like the XR has one.

    That said, it looks like the only thing my XT and the XR engines have in common are that they both have pistons and gears and valves. Everything is done differently.
    I have a manual, but I think I'll be spending some tine in her asking questions.

    I had an 88 xr200 and it was lit from the factory. I sold it 4 years ago and noticed it was forsale again and almost bought it back. its such a fun bike, the older models had better suspension than the new ones. Its the most fun you can have on 2 wheels as far as im concerned.

    Thanks, now that I know it isn't an issue, I can focus on the electrical.

    Update...
    So far I found the the air gap on the pulse generator was too big. I asjusted it and I now have a better spark. I haven't done any continuity or resistance tests yet.
    I couldn't line up the marks on the coil though when the crank was in the correct spot. Either the cam is off a tooth or the timing chain is streached really bad. time to dig a little deeper.

    It is great to see a thread on the XR200. I had a 1980 model and then a 1990 model when I was in high school. I bought the 1990 model new in 1991. They were great bikes! I just bought a 1983 Honda XL200R on friday for $375. It is in excellent condition and runs great, it just needs a clutch. I already have parts ordered and the clutch disassembled. It is a fun project and should be a great little bike! We need to post some pics!

    I've had the best of intentions on getting some pics up. It started with camera troubles, then sick as a dog followed by rain/hail. I WILL get some up in the next few days. Glad to hear you guys love these rock solid bikes as much as I do. I hope it's as tough as my Mini trail 50 & 70 were:D

    What is the oil capacity supposed to be on a xr200?

    1L (just more than 1qt) when changing the oil, 1.2 after a rebuild.
