2003 xr100r wont stay running

Cleaned the carb, the only jet I dont think is clear is the pilot jet (its got such a small hole in it that its hard to clean) everything else is 100% clean. The gas in the tank is a little old as I didint have fresh gas, but she fires up and idles nice with the choke on. At an idle if you were to remove the choke it will just bog and shut off like someone cut the fuel. If I am riding the bike with the choke on, and then switch it off it will run fine untill you loose momentum. What do you guys think I should do, buy a new pilot jet? Thanks

Its your pilot jet. See if you can get a small piece of wire thru it like a brisle off a wire brush. That usualy does if for me. People will tell you not to use wire but I find that sometimes its the best way to clear a jet.

The problem with wire is that it can scratch the hole. The hole is so small that the scratch can affect the size.

yea I know Ive heard that as well. Problem if its really plugged the only answer is to replace it. So at that point you have nothing to loose by trying the wire trick. It it works great. If not then you have to replace it anyways.

And so far I have never gouged up a jet using wire to clean it out. Can it happen..yes..will it..probably not.

I just use compressed air. It seems to work every time.

Last time I tried to shoot 110psi thru a #35 pilot jet I shot it into the darkest recesses of my garage never to be seen again :p

I usually find something like that when I get home with the new one.

zip on over to the hardware store with your pilot jet and look for a piece of Brass wire to poke thru it. Heck when you test the size you will clean it right out and then you won't even need to buy the wire.

thanks for the help. I tryed to use a bristle off a wire brush and its too big for the jet. The jet size I have here is a 35s I guess I will replace it and see if she will run and start easier then with the choke on.

If you have an old throttle/clutch cable laying around try cutting a chunk outta that. The spiral wound wire works pretty well for cleaning out a jet.

well when I was looking in the jet it looked like there was such a small hole in there, impossible perhaps to fit anything through. I was going to go the store, to find some wire thin enough to fit then my dad called me and told me he got it unplugged using a wire. So the problem is fixed and you guys were right

      Wanting to buy a TK link for my '89 XR100R. I have looked on the internet high and low for a used one so I don't have to shell out a ton of cash for a new one. If someone could help me out or point me in the right direction it would be greatly appreciated.

      So I just picked up a 1989 XR100R in awesome shape. I plan to use this as my pitbike/parts getter. I have done some looking around at cool mods people do to these bikes and the aussie lift has come up multiple times. I fully understand how the lift is done but I haven't seen anyone say how long it lasts or if it breaks eventually. Obviously the longevity of the lift mostly depends on the quality of the welds, but are there any inherent risks that come with doing this to the bike? I honestly just think it makes it look better and I also plan to put the front headlight and plate from an XR600R on it as well as a tool bag and a few other things, so my main goal is to make it look like a baby 600. I have had these bikes before and I love how they ride and how reliable they are, I'm just worried the aussie lift may cause me issues in the future. I do not plan to put different shocks on the bike and will not max out the rear lift as to not make the bike super squirrley or twitchy. Any insight would be appreciated and if anyone has documented the process of how they did their lift I would love to take a look!
       
      (For those who do not know what an Aussie lift is: It is essentially relocating the bottom shock link mount slightly higher [most say no more than 11mm] so that the bike sits higher in the rear)
       
      I will post pics of my bike as soon as I get a chance for those who would like to see.

      Howdy.
       
      Got myself a CA-Plated '90 XR100R, which is awesome. Used as my little slam-pig. Fantastic bike.
      ANYHOW; Just raised the front end with some 03' CR85R forks, which was a swap from the 80's disc-brake 19' KX80 forks I used to have on there. 
      (The KX front end wil lbe up for sale soon, btw)
      Just wanted to ask the best possible way to go about raising my rear suspension, and it seems like users have gone 3 ways;
      1) Cut some 7/8 or 3/4 steel plate into spacers and use a longer bolt in the linkage to extend the travel. (Easiest)
      See Link (1)
      2) 'Aussie Mod/Lift' the rear end by cutting and re-welding the linkage mounts higher on the bottom of the frame (Mid-Difficulty) (thank SoCalXR, et-al.)
      See Link (2)
      3) Modify an existing swinger from some other bike, or even a whole new frame (CR85R? / KLX110? / SX65?) to fit, and then running linkless. (thanks SettinTrendz, et-al.)
      See Link (3)
      What do you reckon the best REAR END SUSPENSION LIFT OPTION for a play-bike/Minimoto?
      I'm 145lbs, 6ft tall. (ya, string bean) and before these mods, was riding the bike pretty much as hard as I could. I want something that'll hold up to the abuses of a full size human railing on it off road at the OHV or in the city. 
       
      Thanks ya'll.

      Hey everyone, new member here.
      I recently traded my 2001 Honda 250EX for a 1985 XR200R. The bike is tight all around and looks like it wasn't used much in its life. However, there is a noise coming from the engine that's not from the crank. It's up in the head somewhere. I adjusted the vales and started the bike up, only to hear a slightly quieter noise which led my father and I to believe that it's the Cam chain. If the bike ends up needing one, where can I find an aftermarket chain? I've checked eBay, xrsonly, and the normal part sites and I am not able to find anyone who has a chain in stock. I called my local dealer and they said they could get one for $70, but I just think that I can find it online for cheaper. It doesn't have to be OEM.
       
      Thanks

      Guy's, After cleaning carb. When running at idle I'm getting a surge. I can lean the bike to the right & the idle decreases. Leaned left it increases. This is after cleaning the carb. Throttle is not binding, cable is routed properly, slide is in properly, no timing issues, no valve issues, filter is clean, fuel is new, spark is good, it runs good, plug is a touch on the rich side. My thought is float level off? See a video of this phenomenon at https://youtu.be/K9p4UFtbA4o
