    What gearing and jetting are you using? Bike seems to run perfectly.

    Other than the exhaust tip which basically only a screen for sparking duty, it is 100% stock, gearing and all. That I am sure of because the carb was gummy before this trip and I removed and cleaned the carb. It had the exact jets that it should from the factory. Running at 4200ft in the video.

    Thanks for the comment.

    Comes with electric leg as standard.........:D:D:D

    Lower ride height:..........:cry:cry:cry

    Stick original shock, forks and rims on and an original exhaust and you've got what the XR 400 should have been before it was discontinued......

    Would sell like hot cakes if it had increased capacity to a 450 motor as well.

    We can only dream what could have been

    I missed a XR400 European version (I think) on CL a couple months back. It was an 07 with e-start and supermoto wheel set. Guy was asking a bit for it, but man was it sick.

    I had what I would call a major malfunction with my 400 today... I was on the way home from a friends house which is a hood 20 mile drive and about a mile away from his house I stopped normally at a stop sign, but when I pulled away I got to second and when I pulled the clutch in to shift to third I heard a metal clink noise and the clutch went limp... All of a sudden I now have zero clutch lever and no way to stop at any signs or intersections. At first I thought my clutch cable had snapped but when I got the the next stop sign the truck at the sign decided to stop for a longer than needed stop and I jerked to a stop and of course the bike dies... I figured I would see where it broke while I figured out how I was gonna get going again. Turns out the cable isn't broke, it has to be something in the clutch itself because the part the cable moves is completely limp. I the had to go to neutral to crank it, got a running start and quickly shifted to first and had to avoid stopping at signs and intersections the whole way home... I won't be able to disassemble it until I get off at 6 but I'm worried about what I might find. If anyone might know anything the help would be appreciated. Hopefully you will be able to give me some advice.

    Thanks for the help... I think I can get it fixed if I had the parts... I will pull it apart tonight to see what's broken.

    +1 on that. I've been considering picking one of these up to carry in my tool bag; I've been hearing of these failing a lot lately.

    Noticed my 2002 was puffing grey blue smoke when cracking the throttle,much worse cold than warm engine wise. Also had someone follow me on the trail and he said it puffed smoke when I whacked it good and hard up the trails. So its burning some oil but so far not that I noticed on the dip stick, maybe not too bad yet.

    But I want to tackle it, any common causes for these bikes? I am thinking being an air cooled motor worn rings are probably the cause. I can run a compression check, but just looking to hear from others who may have had the same issue.

    you tear it down that far, just as well service the head too..new valve seals, lap the valves after checking them for replacement etc..just typical top end service..good luck

    Yeah I was considering that. However I've never done head work before, although it seems easy, I would want to have that done and just do the piston and rings myself. Guess it will be a winter project and I'll just keep an eye on the oil on each ride.
