    Most early info said .610 but I have seen several posts referencing .640 as better. I tried .610 and still had a bit of hesitation when hitting the throttle from idle. I bumped it to .640 and the hesitation was much improved. So I am leaving at .640 but who knows, .900 may be spinal tap nirvana :D

    Took the 500 out to Colorado for some skid plate testing :D.

    If you need a right side wing look around the steep section of Black Bear Pass.

    Looks like this KTM part was only welded on the bottom? Something I read when putting the bike together a year a go but I'm old and like shiny metal. Looks like the left side is about to go as well. That's what I did to the right side on Chinaman Loop and finished it off 3 days later in Ouray.

    After loosing a wing off my skid I open to plastic or carbon suggetions. Prefering the best out there to make up for my lack of rock avoiding skills :evil. Anyone running this brand? http://www.ktm-parts.com/KTM-1850.html

    What brand is that one? I have a Flatland Racing aluminum unit on mine which has had some abuse.

    It is hard for me to imagine using something made of plastic, fiberglass or carbon fiber on anything but a track bike. It seems like I would be buying a new one every year after dragging the bike over roots and rocks. Kind of like the annual pipe straightening schedule I had going on my old KTM 200 EXC.

    What the hell am I supposed to do with my free time now that I have finished this thread, Ride? So much info Loved it.

    I have 4 hours on my 13' 500exc. Traded up from my trusty 525.

    I have a few questions:

    New to SF bay area looking for folks to ride with on the weekends. Been to Metcalf and Hollister a bunch I have raced the VCGP the last couple of years and it beat the hell out of me.

    Is there a shop that will load the euro map for me around here?

    Anybody close have the TPS tool? I am running the stock setting and dont have any issues but if it is the hip thing to do I should give a shot right?:rofl

    They work & you will never have that happen again. Plus they protect the clutch & rotor covers. :D

    If you look at the parts breakdown for the 500 XCW, you will find the proper hardware listed to fit into the holes on your 500 EXC. I just ordered them at the same time I ordered all my spare parts. The breakdown may even tell you what size the screws are.

    Is the carbon skid plate quick release for oil changes? I like that feature on the factory plastic skid.

    Hope this isn't a stupid question but will it work on the XC-W's ?

    I would sure think KTM would use the same connectors on the TPS for both models. I guess you could look at both parts fiches. Probably even the wiring harness is the same, with some unused connections on the XC-W.

    Not sure if you are referring to our skid plate or not but...

    We use (2) M6 fasteners for retaining the plate. We found that a good impact could knock loose one fastener & two provides redundancy (like on aircraft). This means that it will take you 2 minutes vs 1 to remove it for the oil change. But also there will be oil in there to change. :D

    Everyone I ride with that uses the factory KTM skid plate with the Dzus fasteners also uses a thick zip-tie to keep them in place.

    I have seen more than one of those skid plates go flying when they take a hard hit.

    I use a Hyde Racing skid plate that's held in by bolts and a backing plate.

    It takes me a couple more minutes to do an oil change, since I am not racing the 6 days international race a few more minutes in the garage is not going to kill me.

    What I find is that I don't get the engine noise coming back up at me with an aluminum skidplate.

    I also find that the plastic / CF skidplates slide over rocks and logs a lot easier than the aluminum ones do.

    Thank You, yes I was referring to your carbon skidplate. I guess that does make a lot of sense. Any of you guys prefer the aluminum plates like the acerbis? If so why? I want to buy one and done.

    Hey guys, just wanted to throw out some information I acquired over the last couple days.

    I noticed that my motor, specifically the valve train was being a little more noisy than usual. So i decided to do a valve check as i just hit the 15 hour mark.

    I cant speak for all the exc's, but i will say that these bikes seem to be very particular when it comes to valve clearance and a noisy engine.

    My 2 intake valves were dead at .100... the clearance is .100 to .150mm

    One exhaust valve was at .115 and the other at .127, range is .120 to .170mm

    I purchased the hotcams valve shim set from cyclebuy.

    The main thing i came accross is that you should check with a caliper before you put them in. The hotcam shims are all a little bit smaller than the KTM shims that were in the bike. So when i first did the change over i went down a shim on all the cylinders. This ended up being too much and the motor sounded like my cummins... lol

    Ended up going back to 2.80 shims, just like the KTM ones that came out. I must say that there is a definite difference as i was able to get the bike perfectly in the middle of spec with those sizes. She runs sooo quiet now and seems to have a bit more torque.

    This is my first thumper coming off riding sportbikes my whole life, so there is definetly a bit of difference when it comes to doing the valves.

    Anyway, ill leave you with a pic of my mostly stock bike... Just has the supermoto wheels, a custom tune, and vanished emmissions. :D

    I just got a box of sexy goodness from Highway Dirtbiker :clap

    I was hoping to avoid a search back through the thread; how do the little indicator lights come out of the existing instrument cluster?
    TIA

    I used a deep socket of the appropriate diameter to support the cluster and then pushed them out. It seems like some of them required a little persuasion with the rubber mallet. They fit right into the holes in the HDB stuff.
