    Unsure. Rad sells their own spacers so my guess is it can be made to fit most Japanese mx/enduro bikes. I do know that it can't be made to fit my ktm which is why I'm selling it. I'm gonna call Rad tomorrow and see how much their spacers are and what bikes it will fit.

    It was a good bike. I still find myself missing it some days.

    Yup fun bike... I just traded my 97 xr4 for a 06 ninja 650. Figured since I rode the Husqvarna all the time and the xr just sat there is trade it for a sport bike.

    Hmm so according to Rad, the only thing it will fit is an XR400. I thought one of the 600 or 650's shared our rear wheel. Anyone know?

    Thanks for that. Looks like it won't fit anything else without some bearing swaps.

    I used an XR650R rear wheel after I cracked My Hub.
    The 650R uses a thicker rear Axle so some different bearings & seals are needed.
    Here is a list of parts I used:

    1 x 91205-950-003 OIL SEAL 25X42X7 (From a Honda Fourtrax 4x4 Steering Stem)
    1 x 91253-033-003 OIL SEAL,25X47X6.5 (Standard XR400 rear wheel seal)
    1 x 91003-KRM-841 BRG,BALL RADIAL (from Honda CRF150F Transmission)
    1 x 6303 ball bearing. (Generic size bearing)
    4 x 90113-MAC-780 ( These Bolts along with 4 washers are needed to fit the XR400 Rotor on the XR650 Hub)
    Easy.

    Was there any benefit in the swap in terms of handling, etc?

    I recently bought a 2000 XR400R, and while I'm familiar with dry sump engines having owned BSA, Matchless, and the XR650R and XR250R, I've never had the oil level measurement issues I've had with the 400. I've read other posts on this thread regarding problems others have had, however, no one has posted that they've used the oil level check bolt to verify the oil level in the sump. I presume, although it doesn't say in the owners manual, that it's checked with the engine off. Otherwise I'd guess that crankcase pressure would blow the oil out.

    So, I'm curious if anyone who's checked the oil level at the dipstick and found it low or not even on the end of the dipstick, has removed the oil level check bolt. If so, was the sump full and oil ran out or?

    I have had four XR4s and have never used the oil ck bolt even once. I can't see any reason for it. Just follow the instruction in the manual and there is zero worries. Can't imagine anything more simple.

    because of the protection I have on the oil side of the motor, I don't use the oil level check hole..it's a pain to remove the armour so all my oil checking is done from up top. Now I will tell you that sometimes, I will check the oil and there will be nothing on the dip stick..this has fooled me a time or two. Best I can figure is that maybe a check valve was open when I shut the motor off and all the oil on the tank flowed out. I learned after over filling to restart the motor for a abt 30 seconds, shut it off and recheck the oil..you may have to do this more than once, but you will get a better and more accurate reading. Hope this helps

    Thanks, but I actually went through all of that already hoping to find a write up but nothing really there in that regard.

    Everything would be awesome, ha.
    I hate going in blind and like to at least look up a write up. I searched the ex forums as well with little info.

    I think my best bet is to break everything down. Look up clutch removal, timing, ect. my maain worry was the fact I don't have timing gun, but from the info I did find it seems I do not need one, just need to align the cam markings and make sure the lobes are facing down and I'm set with that.

    The nut stake and needing a dremel to remove it has be at a loss for the moment but I guess once I tear in to it it'll be self explanatory. Ordering the side cover gasket and crf chain tomorrow.

    Pulled the tensioner off, set the plunger all the way out and could nearly push the tensioner all the way on the jug, so that seems to be my issue. Hoped it was the decomp since it was poorly adjusted..

    When I do the swap, i'll deffinately have the write up since I take pics when removing stuff anyway.

    would love to see your write up..if we can get the stoopid snow to stop so that I can get over to the shop to work on this, I will do so..so I may need a few days to get it done..hopefully, you're not in too big of a hurry for it.

    Hey Doc, what brand is your oil sump "armor"? Is that some SRC stuff? Thanks, Rando.
