    Also picked up some Excel/Talon Supermoto wheels. 17x5.00 rear and 16.5x3.50 front. Might end up converting the front to a 17. I'll see how the slicks last on the street.

    THX! That is what Evil K has now that you mention that. I have it bookmarked but didn't realize it was different than map switch. Is that something that requires Dyno to tune or do they have preset settings? I will check their info... thanks again for the reminder about that.

    What are those tires, and how did you like them? I just ordered some Shinko 705's in 18/21 until I can scrounge up enough coin for SUMOs. Which might be a while after the 13l tank, bash plate, SICASS lights, and the invoice I got from HDB today for the whole shebang on the handlebars....:ear

    Ok I have a question as I have not tried the JD box yet... Isn't the JD Jetting 6x turner for adjusting the "fuel" map and the handle bar mount switch for switching between the "soft / aggressive" ignition map??

    What did those run you? I also did the Sicass LED treatment but only in the rear.

    The CPU has many maps that are overlaid on each other to get the final values for fuel and ignition. There is a temperature map, accellerator map, altitude map, and finally the aggressive/standard/soft maps that are overlaid depending on the external switch settings.

    I believe the 'soft' effects the ign mostly. The aggressive effects both the ign and fuel. But, I also believe these are only available for the SX and XCF, not the XCW and not the EXC.

    The JD Jet attaches between the CPU and the injector. It lengthens or shortens the injection pulse.

    Interested in 500EXC owners thoughts:... not that anyone has had to break into their clutch, but.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>
    <o:p></o:p>
    Through hours of internet and ADV research on the 500exc I'm obsessed- and need to buy one:wink:, though one detail I can't figure out - the new clutch incorporates "transmission friendly back-damping". I assume this is some type of cush mechanism, but what is it? I can't find any pictures or details anywhere. The KTM literature is vague, and I assume no one has had to put a new clutch assembly in their 500 yet to see what's actually going on...<o:p></o:p>
    <o:p></o:p>
    There's definitely plenty of talk that the 500exc may not make the best adventure bike due to lack of cush drive rear hub, and some other small issues like fuel and oil capacity. Just wondering if KTM actually addressed the cush issue from the factory. Definitely something good to figure out before investing money in some Excels.
    <o:p></o:p>
    thoughts? would a cush drive still be necessary?<o:p></o:p>
    <o:p></o:p>
    on a similar note: I also found that many street bikes incorporate rubberized front sprockets. Trying to figure out now if it's actually something that separates the middle from outer splines/teeth, or just rubberized to lessen chain noise. thoughts on that too would be great.<o:p></o:p>

    The rubberized front sprockets are just extra rubber on a normal sprocket to cut down on chain noise. No tranny to rear wheel damping there.

    Best place to look at stuff like this is CheapCycleParts or RockyMountainAtvmc; check their OEM stuff
    NOTE: Number 8 is the Damping Rubber that attaches to the Clutch Hub.....

    Good call SteveO.

    that rubber piece looks fairly insignificant when compared to the amount of rubber, and damping, created from a rear hub cush drive setup. i'm sure this clutch rubber helps a bunch, they wouldn't put it in there if it didn't. though i'm feeling like if 30% of the bike's time (or more) is spent on pavement it would probably be wise to invest in a cush hub. more research...

    The XC4 engine also has a cushioned clutch hub but that isn't enough to stop it from wearing out the output shaft in 10-15 k miles if dual sported.

    If you want to keep the bike a while or ride a lot, a cush wheel is a good investment IMO, and they have great resale.

    How expensive is a cush hub for our bikes? And are different manufacturers for this device?

I had them put barkbusters and new springs to help with my size (265) and pick her up on tuesday. I think im gonna name her Orangejello (oranh-jha low). Anyway Ill let you guys know how it goes - when it goes

    Ok, my hands back up in the air, what is a crush hub? How is it I have lived my life without one yet still ride, eat and breath?

    As stated, and not often enough- Robbinsville, NC.
    You haven't lived your life without one - look at your ZX14 rear hub !
    The rubber dampers absorb the shock of the drivetrain instead of transfering it to your clutch/transmission.

    KTM, RAD Mfg, Haan Wheels and Talon all make cush drive hubs for KTMs. I'd skip the Talon because of the weaker cushion rubbers, the other three all use the same rubbers (at least they look the same to me) so it's a question of bling vs. cost... Figure $400-$500 for hub, sprocket carrier, and rubbers.

    You can also try to find a used wheel from a 640 LC4 Adventure or Enduro (not 690), they had cush drive hubs stock and will fit any EXC. However they used silver DID rims (pretty good) and later ones black Behr rims (weak), so not optimal if you like to match your 500 EXC rim color.

    I do think the 660 Rally came with a cush hub and a black Excel rim, I have one of those here and that's what I was told it was from. Unfortunately not too many of those around...
