    Sorry Bill doesn't look like it.

    A quick check at Munn's shows it was a 2003.5 introduction and the part number for the washer only cross-references to various other models for the same tranmission shaft, not the clutch. For an earlier model, you would need a new shaft to use the new washer and nut.

    I know when I first got my 2006, I didn't bend the washer and the nut loosened with 1000 Km (it was tightened to the torque specs with loctite). Did it back up, and bent the washer and no more problems, EVER! And I have even re-used the washer several times.

    Came upon an interesting product today: a wide band Air/Fuel digital gauge plus sensor and controler for 200$.

    I'm wondering if this would be a good thing to add to the lc4 for my coming trip.
    Since the bike will be going to lots at varing altitudes (front coastals to higher regions of patagonia) and me not being use to tunning carbs. Would having a display telling me just how lean/rich the mixture is help in keeping the carb properly setup?

    And if so, would the 14.7 to 1 (i think) be where I would want to keep it at all times or would I rather err on the the rich side a bit?

    The short answer is no.

    Lurkin in here as usual. Quick question for KTMBill, then I'll get lost as not to jack the thread. Up on post #18, Bill recommended bleeding brakes with dot #4. My 2000 uses dot 5.5 which is a silicone based fluid. This is not compatable with the glycol based dot #3/4 type fluids. Did KTM change the spec fluid over the years? Am I missing something here? Don't mix 3&4 systems with 5. Just sayin.....Thanks guys, I now return you to the regularly scheduled banter..:lol3:rofl:lol3

    Fast,
    The top lid on my handlebar reservoir, '02 640a, says "Use Dot 4 Only".

    I used some Dot 3 cause I was leaving for Central America and was in a rush. I lost the rear brake completely coming down a volcano to Lago Atitlan in Guate.

    Problem cured with Dot 4.
    Speciality item in Guatemala small towns.

    Scares me to see blown out USA school buses coming down the mountains with Dot 3 in the system, teen age drivers shifting gears like crazy.

    DOT 3, DOT 4, and DOT 5.1 are compatible, the higher number the higher temperature tolerance but not necessarily "better" depending on other characteristics. You can go higher than specified (eg use 5.1 in systems marked 4) but should not go lower - as Bill discovered when using his bike hard.

    DOT 5.0 is the silicone-based stuff and can't be mixed with the others without proper flushing of the system first.

    Yup, you get the ceegar! Says right here that you can put dot 5 in a 3/4 system with proper flushing of the system. http://en.wikipedia.org/wiki/DOT_5
    There are advantages to dot 5. For those intrested in conversion, read up on the term 'proper flushing' before trying this at home. It also appears KTM has changed the brake fluid spec. sometime after 2000. Thanks guys. :freaky

    DOT 5 is a bad idea because it is not hygroscopic (i.e. does not hold moisture in suspension).
