    Rule of thumb for sag is 1/3 total travel. If you've got 12" of wheel travel to want 4" of laden sag ( you on the bike). 9" of travel, 3" of sag...and so on.

    If you road ride or use luggage a lot you'll appreciate a stiffer preload than 1/3 sag. If you like popping wheelies, or just want it to come up easier, stiffer shock preload helps there also. 1/3 is a good starting point, but it's not set in stone. Careful on the internet....some folks will have your thinking if your sag is 3mm out that the bike will inexplicably become a deathtrap or something :D

    Thanks @NSFW

    I will see what all I can find. I've just been playing too much on atv trails with a friend on a raptor, so I'm riding it pretty hard at the moment.

    I know the preload is off because the previous owner had it set for 20lbs heavier than me.

    On the XR I decided to remove the nice / new fancy IMS gear shifter installed by PO ... I know was replaced because after a fall the stock was bent and trying to bend it back broke.
    I think rather have the less strong original shifter even though is shorter ... :-) XR400R 13.jpg

    As long as your foot is Happy and it keeps it's way out of the case, name means squat. I only run the IMS because it is perfectly placed for my dirt or street boots.

    On my XR600 I knocked in a alum plug for the tip. The extra 1/4 keeps.me from miss shifts

    Replacing bent shift shafts = no fun.

    Yep, hence the value of the soft, malleable Honda shift lever. It takes the brunt of the damage so the shaft doesn't have to.

    Hi,
    I have an electric start XR400 listed for sale in the Flee market. It's located in Las Vegas.

    I think all XR400s have the same Keihin carb, just different jetting from the factory. The choke lever has 3 positions, and it is on the left side of the carburetor.

    I've got a mikuni, but the Oz OEM carb has the choke on the side, too.

    That's not the choke on the clutch lever, that's the decompressor lever.

    The choke is on the carb.

    Yeah I'm aware where the choke and decompression lever are on North American XR400s, just wondered if the Australian road-legal versions had it in a different spot.

    XR650Ls have it on the clutch lever like so
    [​IMG]

    CRF230L and CRF230M also have it located on the clutch lever, whereas the standard CRF230F has it on the side of the carb.
    XR250L have a push/pull knob next to the ignition and under the gauges, XR250R have the usual lever on the side of the carb.

    Happy Memorial weekend to everyone ...
    Finally last week trailered my XR to a friend that has the toy hauler and we were on our way out to the desert ... California City.
    The 400 performed flawlessly and I've had a blast with it ... really glad made the switch to original shifter lever. Back home now safe and sound and thinking about the next time out.
    No humans or machines were harmed in this adventure! :rofl

    I used the Motion Pro cables on all of my XR’s. They seem to have cables for everything.

    After last weekend ride emptied the gas tank, carburetor and ordered new rubber.
    Installed a clean UNI and waiting on inner tubes. Also today started it, to make sure everything was in good working order.
    Goodies are arriving already ...
    As soon as tires are installed will be ready for the next adventure! :-) XR400R 16.jpg

    I lost my patience with the rim guards years ago :D Unfortunately, my rims show it, but I can't see it from the saddle :ricky

    Bike looks good, man!
