    Anyone used the PC Racing FLO PCS1 spin-on oil filter?
    Specifically, I'm wondering if that's the correct one for a 640 Adventure. There is some confusing information about what exactly it fits, as in, fits a Duke 640 and a 990 Super Duke - huh?. My 950 is the same basic engine layout as the 990, and there is no spin-on oil filter of any kind.

    I actually have been using a scotts stainless spin-on for many years, and it works great, but is very difficult to get off (no nut), and more difficult than it needs to be to take apart. The PCS1 looks easier on both counts, if it's the right one.

    My 2002 KTM 640 sight glass is spraying out oil. I can't find the part number for the sight glass on any of the online part finders?

    This is what I come up with for the stator side cover..

    Unless you've got a site glass on the left side of the motor, then you've got a clutch cover from a newer bike.

    Still checking out my new to me 06 Adventure... It looks like I have a small oil leak right above exhaust/head area. I have not pulled the tank yet to check it out. Is this a common leak area? Rocker arm cover? Possible other leak areas?

    An easy fix. The exhaust stud on the left side of the head is threaded all the way into the wet part. Pull that stud and apply some 5770 Loctite thread sealant on the threads and reinsert. Presto chango-the fix is done.

    The other place is at the counter sprocket-an easy fix, the other two places are on the rocker arm shafts as they exit the head above the spark plug.

    Counter Shaft-replace the O-ring and pick up a few more as spares for the clutch slave.

    The easy way to address the rocker arm shaft seep is to run a bead of an oxime cure (sensor safe...important it says this on the tube) RTV on the end of the shafts. The more in-depth and correct fix is to replace the O-Rings.

    I have the first year 640 (Actually a 620) and on long rides, my hands REALLY buzz when first off the bike. I have anti vib mounted in the bars, but I seem to remember a post sometime ago on foam rallye grips? Does anyone know anything abut these and where I might find them? Thanks!

    So, has anyone successfully replaced the shift shaft seal without splitting the cases? Mine's got a slow drip. I've clean and then replaced the v-seal that rides against the shift lever and cleaned the area behind it as well as possible with silicon spray.

    On my bike it looks to me like the seal is cocked in the bore and that a suitably small puller could reach in there and grab it out.

    I've fitted Symtech grip heaters to 3 different bikes now & we really like them. I find the 2 heat levels to work well for me. Insulate under the clutch side one with adhesive lined heatshrink. Only issue over many miles of use has been the plastic rocker switch that came with the 1st set which crapped out - get the metal toggle switch.

    Check the wiring to the clutch lever sensor too - this is more likely to be the issue than the sensor itself in my experience.

    Cheers

    Hi AdvRiders :)

    Here is my fathers 98 Adv R.

    Could You help a bit, to get this thing run properly:

    as I alreday wrote on ktmtalk:

    It's very problematic to start after winter, last year everything was OK:

    a) fueal is fresh
    b) new spark plug - NGK D8EA
    c) changeg spark plug
    d) carburetor is Dell'Orto PHM40SD, disassembled an cleaned few times - there everything must be OK
    e) valves OK, and no air leak.


    Is there common stator problems to LC4 as RFS have? I'm thinking that spark is too week!

    and is possible to start bike only with kick and without choke, if turns choke on running bike it dies immediatelly. When it's running - runs and idles well at 1700 rpm.

    Feels there is no fuel in float chamber. If sqiurts right in it or squirt in inlet tract bike starts good with kick.

    Any sugestions?

    A lot of starting issues like your having can be chalked up to a poor battery... If the battery is good then the next thing I would look at is your starter sprague clutch, is it slipping and not giving the engine the proper spin when the E-start button is pressed...

    You mentioned that you cleaned the carb, did you make sure the pilot circuit under the pilot jet is clear? If there is a clog in the passageway itself the bike will not run correctly at low revs...

    But runs well after warm? Sounds too rich. Check float height.

    Big box,
    Another bump for your Easton bar question. I don't know the answer.

    For the heated gtips, never used a heater system with foam grips, always used hard rubber type grips.

    So I will ask, is anyone using foam grips with grip heaters?

    The inner face (alloy) on my rear brake caliper has worn due to the pad vibrating against it over time. (Possible due to worn brake pad retaining pin as well)
    This causes the pads to wear on an angle and wear out prematurely.

    Bike has done 60000klms.

    Any one know of a reasonably priced aftermarket caliper?

    Ignore the dirt, but tis pic shows whati mean.
