    The one I use on my XR400 with a big ass gas tank on there is 115 mm long and it is pinched down on the end and has a M12 hex which I have shortened some...it could be shortened even more to get to 113....then use a m12 box end, or better yet, one of the ratchet box end wrenches. This one was in the XR400 tool kit...and is the same one used in the pre-1996 XR250R's...i shortened it because getting back in there with that big tank is a PITA...the one wallrat shows is almost a PITA because with those holes and the crossbar it'shard to get 90 degrees of rotation every time....and the plug has LOTS of threads

    I start my plug with about 3" of 5/16" ID hose over the end as an extension on the plug

    Installed a new rear tire on my '96 XR400 yesterday, and got her loaded up in the truck to ride this weekend.

    Today, walking behind my truck, I grabbed the rear tire and there is some play at the axle, not much, but enough to notice.
    I remember torquing the axle nut pretty snug last night and every looks ok...

    Anything obvious I may have missed? First time I have pulled the rear wheel out of this fairly new to me bike.

    Rear wheel bearings? If you grab and can move the tire sideways, should be those shot.

    1/2 turn is all that is recommended on a new plug, and 1/4 turn on a used plug. Mine is cake even with a Clarke 3.8 tank on the bike. I put the plug in the tool, slide it in diagonally, turn by hand until it stops, insert the little rod thing, and rotate 1/4 turn. Your tank must ride lower than mine cuz its honestly one of the easier plugs I've dealt with on a bike.

    The wheel worked great. I wouldn't be selling it at all except everyone and their mom is telling me I should run a MT43 trials tire whenever I complain about my DS tires not lasting that long on the street. Unfortunately the MT43 only comes in an 18" so time to swap wheels. I ordered the exact same wheel but in an 18 if that's any testament to what I think of the quality of it.

    If on the other hand you're asking about the Shinko trials tire that's mounted in that picture, well then it also worked great - for 250 miles and then it split at the base of several knobs and wouldn't hold air anymore.

    Ah, that makes sense. If I wasn't about to go to a MT43 on the rear, I'd be buying your tire tonight. :cry

    Haha right on. I'm actually thinking I might keep it and put a paddle tire on it since I hit the dunes fairly often. Only have 1 quad right now so if the wife is riding that then it'd be nice to have the XR setup to ride as well.

    ok so it was really windy the other day and my bike fell over on to its right side. now the kickstarter is not returning to the top after you kick. it still starts so im guessing that something became unlodged in the fall. its been shit weather ever since so havent been able to take it apart for a look. is this common/easy fix?

    cool to live on a boat, sux no garage or shop!

    you will have to pull the clutch cover (kick start cover) and see if the spring on the kick start shaft is either broke or slipped off the spring perch..this means that you will have to drain the oil and get a new clutch cover gasket and any other gaskets and O rings that you will remove..cheaper and less hassle in the long run, to replace em all while you got it down..good luck!

    I tried searching this thread a few times and didn't get what I was looking for so.... I have a 99 xr4 that recently got plated. Now I have two areas that I would like some advice in. First has anyone or does anyone put a key or toggle switch to deter theft, and if so were did you place said key/switch?.
    Second, what is the preferred sprocket sizes for somebody who is looking at less and less single track and more slab and gravel/ woods rd. Thanks for any insight

    I got the Baja Key switch and I mounted it up on the handle bar clamp on the right side..real easy.

    I run a 14/46 tops out at 60mph...makes for a long day on pavement, but PERFECT for any dirt road and works great for any trail too!
