  1. Hi, I posted the same question in the crf250x forum, but I thought that I would post here too, since it is related to putting crf forks on my xr400... Could someone do me a favour and measure their crf250x front axle please, if you have one fitted as part of your fork conversion? The specific measurements that I would like are: - Length of the shoulder - Length of threaded part of axle - Overall length I purchased an axle from eBay, which supposedly came from a crf250x, but it doesn't quite work out... I have an axle from a known crf250r, which, in conjunction with my 250x wheel and spacers (one of which for the speedo drive delete) all works out and mounts up fine. When I switch-out the 250r axle, for the supposed 250x axle, and swap out the speedo-delete spacer for the 250x speedo drive, it seems that the shoulder of the axle is about 5mm too long as it hangs out of the fork leg clamp, and not enough of the threaded part seems to protrude from the left hand side of the fork. Thanks in advance. Yooj

    Xr400 supermotard oem harness

    Hey all, I've been reading forums till my eyes bleed. But there's no 100% writeup with pictures on an xr400 electric start conversion...I was thinking of biting the bullet on the oem honda xr400 supermotard harness, as this is already outfitted for turn signals etc. Will this work with the Honda trx400ex stator,cdi,etc? Also. Does the INNER left hand case need to be swapped from the 400ex, or just the crank and OUTER case cover (stator cover) ?any help is greatly appreciated..

    1998 XR400 Kickstarter

    Hello, I'm new to the forum and new to Dirt bikes. I have an issue I was hoping someone could help me with or give me advice. I picked up a 98 XR400 for 200 bucks but the teeth on the kickstarter joint is rounded off. I put a 2002 xr250 kickstarter on it and it fit around the spindle but it wasn't very practical for permanent use, there's certain clearance issues. Anyways it fit well enough to get my XR400 started up in two kicks. Knowing that the kickstarter has been discontinued for this year. Does anyone have any new information on a kickstarter from another bike or year model that will fit on a 98 XR400? Maybe any leads on where I can buy a 98 kickstarter?? I've read the postings on this same issue and I'm aware of the modification that can be made but I really don't want to do it, at least not right now. Any help with this would be greatly appreciated! Thanks

    What beta to buy

    This is my first post so hopefully I have this in the right area. So I'm looking to buy a new bike in a few months and can't decide what Beta to buy. I am going between an xtrainer, a 300rr or the 390rs. I know they have slightly different areas that they excel. I am coming from a 1998 xr400 and an xr250. My question is do any of these new bikes I am looking at have good off idle torque, like slow speed tractor torque. Both my xr's could chug along and climb almost anything but they are heavy and getting older. I dabbled in trials for a bit so I really like the low end pull of thoses 2 strokes, but I also have had a few mx bikes that had nothing down low. What are the beta 2 stokes like. Also does the 390 have a pretty low first gear if I go the 4 stroke route. I ride some pretty rough single track in Georgetown ca if anyone is familiar with that. Lots of switch backs and no room to get speed over some of the obstacles. I am more of a technical rider, don't do much high speed stuff so I'm not to worried about the soft suspension of the xtrainer. For backround I am 200 lbs, 6ft, I'm a decent rider but don't race or anything. I have had loads of Japanese bikes and I am wanting to try out a European enduro, this would be my first new bike. Hope the post isn't to long. Thanks

    xr440 top-end rebuild

    SO I'm having my top end rebuilt - one of the exhaust valves is clearly dumping oilso Im sure the valve is done and/or valve seat. So far I plan to have the following replaced: (Used parts) Cam (staying with stock and the one I got shows very little wear) Head (found a used one on ebay that looks to just need some lapping) Rocker Arms(on the used head) Head Cover (New Parts) Wiseco 440 top-end gasket kit Kibblewhite Black Diamond Valve kit with new springs, seals, etc New Cam Bearings New sparkplug. Am I missing anything for the rebuild and while it's open, should I consider doing any other work? thanks!
  9. I've been seeing a "Camel-toe" device that is essentially a large side stand foot plate for adventure bikes. ITs primarily used in sandy or loamy conditions where a traditional kickstand would sink into the earth. They have them (understandably) for the KTM, BWM, Triumph but does anyone know if they have one for the XR series bikes? I've looked all over but have not discovered one yet.

    Xr400/250 supermotos

    Every one post their pics of your supermoto! I'm just trying to get some ideas on what to do next! I just orderd the 36mm pumper carb from XR's only, and tonight I am going to order some under bar mirrors! Here's what she looks like right now
  11. Thumper Talk newbie with a question about my bike. I just bought a 97 XR400 with electric start, stock motor (not built) stock exhaust (but the center tip missing) and a Mikuni Pumper Carb (air box is open from the top and side). I am assuming the carb is unmodified from XR's ONly but the previous owner said he never got the carb/bike running right. I wasn't sure what to make of that but after taking it out for a ride the other day I noted that the bike sputters when I was buzzing down the highway at 60 MPH/2500 feet in elevation. Also, the bike doesn't seem to respond immediately when I blip the throttle to get over a rut in the dirt road. Not really sure where to start. I looked at the spark plug and it looks like it's not fat or lean, so I am kinda at a loss of where to go next. opinions would be appreciated.
  12. I want to know which headlight to buy to increase the brightness and quality of my headlight. This is my configuration. I just upgraded to a RickyStator dual stator. The previous owner installed a Baja Designs dual sport kit. I successfully installed the stator, the DC system works great working my turn signals, and tail light. As for the AC circuit, I wired the BD Headlight direct to the stock green (ground) and blue (hot AC) wires, and it works. In order to get the high low beam working, I have now ordered a relay switch to allow the light to go high beam and low beam. I've read that I can use a 100 w lamp now, but I don't know if this is halogen, LED, or whatever. I'd really like to know what you recommend.

    Xr400 supermoto frame sliders?

    Does any one have frame sliders on their xr400's? I have been looking for some, and I don't want to do the skate board wheel trick.
  15. I just bought a 2002 honda xr 400r about a month ago. it has an fmf power core 4 muffler and fmf power bomb headers with 54/142 carb jetting. Ive changed the oil with honda hp4s full synthetic oil 2 times now(1 time to flush out whatever the previous owner ran). I also added lucas motocycle oil stabilizer.also I know for a fact I added way too much gumout tune up in a bottle to the fuel so I dumped the tank and carb and refilled with the same exxon 93 octane fuel as before. so now heres where my problem started, I washed the bike the other night and sprayed out the spark plug cavity for a good 1-2 minutes after changing the plug earlier that day. I cranked it up and smoke started pouring from around the headers and coming out the exhaust as well. it also started sputtering and trying to die if I didnt give it any throttle. ever since then theres been smoke coming out of the exhaust and the sputtering/need for throttle to keep it running. after it gets warm and I ride it around for a few minutes its fine. the smoke is white and only comes out for 30 seconds max and the sputtering lasts about 1 minute until its warm. did I get water in the head from spraying out the cavity? is the oil additive causing the smoke and sputtering? did the gumout tune up in a bottle cause the problem? did adding the extra 12 oz of stabilizer over fill the crankcase and cause the problem? bottom line- WHY IS MY BIKE SMOKING AND SPUTTERING ON COLD STARTS??!?!? sorry if this is a random string of questions my brain is just fried at this point...
  16. Hello, I have a 1989 XR250R that I am going to convert to a dual sport. I ordered the Tusk lighting kit and the drum brake switch. However, I do not know how to install the front brake light switch. What part would I need and how would I install? Sorry I am a noob. Thanks

    removing cam chain tensioner,

    Hey guys I am wanting to take out my cam chain tensioner and give it a look over for wear. Do I have to have the bike @tdc or any special position to remove and replace the unit, Or can it just be removed and replaced? I just checked my valves and doing some other maintenance and just feel like checking the cct. Thanks!
  20. Recently I've found myself playing with a few older xr's. Currently I have an 86 XR200 and an 82 XR250 that I ride in vintage enduro events. Most of these shock absorbers are turfed in favour of a later model shock or something 'rebuildable'. The gas canisters appear to be fully sealed and non-rechargeable. I couldn't really find any info on this, so thought it'd be worth posting what I've found here. Rebuilding these is no more difficult than rebuilding any other XR shock. These DO have a schrader valve - it's just hidden under a tamper proof cap. See pictures below. Standard shock canister: The tamper proof cap: Small hole drilled in the cap - just large enough to get a screw driver in there to lever the cap off: Cap off: Bladder 'cap' tapped downwards lightly to reveal the circlip: Bladder removed: The rest of the shock rebuild is the same as any other XR. The canister is the only difference worth noting in terms of seal head replacement between the earlier and later models. I've been unable to find a listing for the shock seal head, but have successfully used All Balls and Moose kits P/N 37-1010. I believe the only reason they don't have a listing is because Honda stated that they weren't serviceable in the early pro-link days.

    XR400 will not start

    O.K. guys, I know that this topic will spur many different responses with many different suggestions so I will give as much info as I can: I just bought a 2001 XR400R a few days ago when it ran fine. After a two-hour trip in the back of the truck, it will not start. I completely drained the old fuel from the tank and float bowl and added fresh gas. Then I checked the float bowl drain and there is a constant supply of fuel. I cleaned out the air box and installed a new UNI filter with a light covering of oil. The fuel screw is 1-1/2 turns out (stock). The spark plug sounds like it fires but I'm not sure (I cannot get it out to inspect it; I have a XR400 spark plug socket on the way). I'm completely lost on the idle adjustment screw---the mud mark on the screw shows it not even touching the throttle valve (!?) so I don't even know how it worked before. Needless to say, the bike doesn't start where ever I adjust the screw. It gets good compression, and the decompression lever seems to be operating normal. I try to start the bike per the instruction manual (full choke, TDC, kick) and after a few times the bike floods. So, I'll pull the decomp and kick through 6 rounds and start over. Sometimes while kicking through with the decomp on the bike will let out a loud POOF of air. Let me know what you guys think. My next move is to pull, inspect and replace the spark plug. If that does nothing, then I'm going to pull the carb and completely clean and rebuild it.
  22. While I was perusing the classifieds here I saw an ad for a Revloc auto clutch. What?!? Guess I've been asleep for a while as I didn't know such an animal existed. I know we've had auto clutches for my little CT70 but never heard anything for a big bike. So has anyone used one on their XR400? There is also the EFM Auto Clutch. Any insight to be shared particular to our bikes? http://www.revloc.com.au/ http://efmautoclutch.com/dirt
  23. I have a pretty crazy problem. This has probably never happened to anyone before, but here goes..... I own a mint 1987 XR250R. The bike maybe has 20-25hr on it. It ran fine when I bought it in the Fall. I pulled it out to start it. It started after a few kicks, however on the return of the kickstarter it somehow rotated internally to the left and now it is caught behind the posterior portion of the frame where the exhaust bolts on. When I say caught, it may be more accurate to say completely jammed.I took off the exhaust in hopes of creating some room to move the kickstarter down and out, but this did nothing to help my cause. I cannot push the kickstarter down any further- it feels locked and I don't want to break or bend anything. I thought to pull kickstarter off and I can't. The top portion of the kickstarter lever is f'ing wedged in behind the posterior portion of the frame and won't allow me to simply pull off the kickstarter at it's base. I can only pull it out so far and then the top part of the kickstarter lever wedged against the frame stops it. I did see the screw on the kickstarter top portion where it attaches to the base of the kickstarter. I took this screw out thinking I could 'tap' the kickstarter's top portion off. The top portion looks like is should come off not problem, but it won't. I'm not sure if it simply slides on or slides on and then locks into position with a twist. If it locks with twisting, I have no idea which way to turn it. I do have the factory service manual, and I'm surprised it shows nothing about the kickstart lever coming off. I've hit YouTube and can't get anything. If anyone has any ideas, I'd really appreciate it. I apologize in advance if this sounds ridiculous or is a purely elementary fix for someone who's very experienced / mechanically inclined. I'll be the first to admit I am no motorcycle mechanic but can usually do most stuff without incident. Warmer weather is coming to Northern NY and I just want to get the bike ready to go. This certainly isn't helping matters. In addition... the bike started and made are really odd noise after the kickstarter got wedged on its return stroke and then died. I'm hoping it doesn't mean something horrific just happened. Thanks in advance for any info. At this point anything is better than what I'm doing. I know being Sunday afternoon, odds of getting responses are pretty low....

    xr426 kit 88mm over bore

    hi all, im installing a 426 kit on my 400. i sent my cylinder and head off to the shop to get bored/rebuilt. from all my research i thought that i could get the 88mm overbore without having to resleeve. the shop insists that 87mm is the max overbore for the xr400. can anyone confirm this? id like to avoid having to pay for the resleeve as well.
  25. As the title states, I am in need of a replacement float bowl for a Mikuni TM 36-68. I cannot find a supplier who has access to or can sell me just the bowl. Any leads on where to look for such would be appreciated. Or if anyone has a messed up carb of this nomenclature that they are interested in selling or just the bowl, please contact me. Tom PS Anyone have any experience with repairing such a crack in thin aluminum casting with metal/epoxy compounds?
