    Clem, I folded up a little tray from some scrap aluminum that fit the battery just right and mounted in the top of the airbox where the snorkel goes. I then cut the five 1-1/4" holes along the top right side to let the airbox breath better. As long as I stay out of deep water, the holes work fine. I mounted the Reg/Recon the frame backbone near the coil. I don't have any good pictures of it but it worked well.

    I hope this helps. Later Travis

    Looking for choke plate return spring and cover for my cb125. Have been up since 4am searching net and parts. Looks to be the same as one on my xr400 so I posted here. Keihin pd carby.

    The 6 shim mod is really for enduro style technical riding, roots, ledges etc... if you ride allot of whoops it's probably going to be a little soft on compression. In technical terrain it will soak up bumps allot better with less deflection.

    I don't see why the method you described shouldn't work. I popped mine off with an air gun, I use that method on allot of forks and haven't jacked one up yet. I purposly use an airwrench that isn't real strong and I'm used to it, crankin the compression valves off with a honkin gun you're not used to could definately cause some issues.

    An issue, I want to be able to put it back on without disassembly. I think all the stuff should stay in place....but no cartridge holding tool. What I'm asking is if the friction from the spring with the forks upside down will hold the cartridge enough to get to the 34 Nm specified?

    I took the forks apart Saturday with the air gun, easy. Putting it all back together required a tool I made out of a piece of pipe. If spring tension is all I need, when I go out camping I can screw with the shim removal and not have to mess with pouring back in my already clean oil. I can screw around with the shimming I like. Having an air gun camping will be more trouble than its worth as I wouldn't want to put it on that way and risk stripping it and running the motorhome engine for the air supply is a pain.

    Should be a major improvement on rocks? Seems ok now but more is better!

    No. You will need to assemble with a air gun. You can mess up if you don't know what you are doing.

    I dodn't have oil in it at the time but I threaded on the top cap, turned it upside down, started the compression unit by hand then compressed the forks and hit it with the gun. I was able to line up the lower end of the dampening rod with my pinkie prior to starting the compression stack, I don't even own one of those tools.

    THanks, I got it. I see I may need the impactor to turn it enough to get the friction to 34 Nm. I can do that easily without the other tool. Might screw with that next time out. Thanks, btw your videos are interesting, especially the Moab stuff. New Mex like that? Might have to put that on my to see list.

    No muss, no fuss. Some gloriously appreciated previous owner removed it and greased it years ago, and it came out this afternoon with minimum hassle.

    When I pushed it down and hit it w/ the air wrench, you could feel it turning the dampening assy inside initially, I just compressed it a little more and it snugged right up, you can torque it but I didn't, it was easy to tell that it was tight.

    The air gun wasn't very powerfull and I set to low torque.

    Adding my name to the XR4 riders proclaiming the value of having the outermost clutch plate indexed correctly (staggered).
    It drops into gear more smoothly, and it's easier to find Neutral at a dead stop.

    Hey Doc when Travis put the new rear spring on my XR he said the bolts for the bring were still nice and oily. He did not try the swing arm one but said those moved so easy he figured the swing arm bolts had to come out nice and easy. Still need to try it but i have some hope.

    Doc is the man with the XR's. I am glade he lives in AR.

    For all you XR400R fans, there's an almost mint condition one on consignment in San Rafael, CA. Head over to Mojotown for a look-see (I have no affiliation with the store, apart from being a very satisfied customer).

    Help! Anyone have an Edelbrock Pumper Carb with a spare 16 or 17 needle? I love the carb but Edelbrock stopped making them and are running out of parts. All they had left was an 18, and with it all the way lean it still runs way too rich. Thanks - Doug
