    Actually, you'll want to check it immediately. The longer it sits, the more oil will/can drain out of the tube and back into the engine and give you a false reading.

    I believe the owners manual says to check it at an Idle with the engine warm. Thats how I have been doing it and I've had no issues.

    From the 2001 manual (note the end of step #3):

    Thanks for all of the replies guy's it's very much appreciated.
    Would you recommend the dye thing ? or to put it differently would it cause any harm? as I really would like to be able to definitivley see the oil on the dip stick, and I think that it's so clean that it doesn't show.

    OR

    Assuming that I'm correct is there another way of tell whether it is present?

    I'm not trying to be a smartass, but take the dipstick out and wipe it dry. Reinsert it. If there is oil on the dipstick it will be wet. If not, it will be dry. Am I missing something? If it is so thin that it is hard to tell, you need some thicker oil in that thing! 20-50 is recommended for summer months.

    If it's present you'll see it on the dipstick.

    I recently purchased a 2002 XR and one of the things that amazed me is the original order documented every single service, kept every single receipt up until 2011. He mentioned greasing the linkage back in 2006 and 2009 but wasn't sure if that included the swingarm bolt. So I broke the bike down before even riding it with some worry.....well I must be the luckiest guy in the world or got the last of the great XR's.....

    I just took all my linkage apart. Everything came off easy, everything had been cleaned and greased by someone before me. No rust, no corrosion. NICE! Just need to regrease it all and slap it back together.

    i need some help on my friends xr 400.im putting a led light bar on it for him like the one i put on my xr650l but from what i understand its a ac not a dc system so i cant just hook up to the head light .i would like to put a switch in line with the head light so i can run one light or the other not both at the same time.im using a dtdp switch on-off-on.any help would be nice.thanks
    it a 04 if that helps at all

    Incandescent bulbs aren't picky, but you'll have to wire the lighting circuit through a Rectifier in order to run LED's. Rectifier = converts AC to DC by running the current through a bank of diodes. Diodes function like one-way valves, allowing current to flow one way, but not the other.

    Guys here's an odd one - my clutch started having issues so I took the cover off, and the pressure plate bearing came apart :huh and was binding up the pull.

    Anyone ever heard of this ???

    I've always dealt with clutch not disengaging fully all the time and hard to find neutral. Ordered OEM clutch discs off ebay as well, but wondering what in the world would cause the pressure plate bearing to fail

    Thanks

    Yup, LEDs are DC, you'll need a rectifier and a capacitor a the least, expect a flicker in the LEDs at idle with the cap. A battery is preferable for good light, it will supply power at idle when the stator's output is low. Some LED controllers (circuitry in the LED unit) can be picky when it comes to the DC power you supply them, if that's the case you'll have to go the battery route.

    Here's a simple Rec/Cap setup

    Just joined the XR4 family! I gave up on my 88 XR600 project and just bought a running, complete bike. Came with many upgrades and two sets of wheels (SM and Dirt) full dual sport electronics kit installed and ready to ride!

    The plot thickens..

    Upon examination, it appears the previous owner installed what looks like a Hinson basket (score!?) and I have 7 and 8 discs/plates instead of 6 and 7. You can see the bearing that fell apart in the second picture on the left. Things are starting to make more sense. Clutch hub doesn't look stock-colored either..

    Anyone heard of extra clutch plate/disc or got any input?

    Springs are at 46mm, don't look stock (yellow colored)

    no wonder I can't find neutral on the bike :rofl
