    400 exc Valve Adjustment

    Also, don't forget to set the radial axial clearance for the rocker arms: Setting Rocker Arm Axial Play When I first checked this on my bike at ~90 hours one was totally tight and the other about twice as loose as it was suppose to be. It's quite simple to do, and now my bike runs like a finely oiled sewing machine.

    how many hours before valve check?

    I did my valves the first time at ~10 hours and they definitely needed adjusted. Now I do them ~every 30 hours which seems fine to me, but I'm not a racer or anything, I just ride for fun and scenery.

    It means you can use it in your KTM which has a oil bath clutch.

  7. Hey G-man, how about a ride report on how your KTM 525 performed on this ride?

    Just depends on whether he ever titled it in Colorado. I titled mine so that I could hook up loops with a few miles on the highway. Only takes a rear light and brake light, headlight, rear view mirror, horn, and proof of insurance (and pay the sales tax) to get a plate in Colorado. If you have time you might want to just pull the carb and see what's in there before you go and compare it to what the Owner's Handbook says. I think that the standard fix without a JD Jetting needle was to simlpy raise the needle two clips (for sea level) from the factory OEM setting and adjust the idle mixture as I described. What elevation will you be riding? Also, there's suppose to be a cold front coming thru so the temps might just be in the 40-50's. If it were really lean you would probably have some really loud popping on decel and the pipes would be noticably blue for a ways around the bend in the headers. Good luck!

    Are you sure that the jetting is stock? It's hard to believe that the previous owner didn't already burn up the engine riding in Arizona in the heat with stock jetting. I'll go out on a limb here and guess that the dealer did something already when the previous owner bought the bike. How blue is the header where the exhaust exits the engine? How's the spark plug look? Always adjust the mixture screw for fastest idle for the elevation that you are riding at, and if you are worried then another 1/8 -1/4 turn out probably wouldn't hurt anything. But raising the needle a clip might be a better idea. You can rotate the carb and get to the needle without taking the carb out of the bike, but it's easy to pull the carb too. I jetted my bike 17-18 times before I finally settled on the optimum combination, using the JD Jetting needles of course. JDJetting That said, I'll still bet that the original dealership already did some changes to compensate for the OEM jetting, and all you need to do is adjust the mixture screw for fastest idle. Just don't blame me if I'm wrong.

    Taillight on 02 520 EXC?

    The taillight bulb is a standard dual filament 1157 automotive type bulb. The parts book shows it as a 5/21 watt. So when you put on the rear brake with your 55-60w headlight, you're at 76-81 watts which is near the limit of the 80 watt stock charging system. You need something like shown lower down on this page: LED 1157 brake/Tail Light Replacement Bulb Perhaps this is what you already have in your XR and you can just switch it out? Any automotive 1157 LED bulb should work.

    02 520 EXC Headlight question

    The suggestion above yields ~110 watts. If you really want some serious lighting power, say 270 watts, look here: Electrex Stator Kit Look here too: Replacement Glass Lens for KTM

    02 520 EXC Headlight question

    Parts manual says it is a HS1 halogen bulb, 35/35w I believe. I simply wired the headlight so that the high and low beam are on all the time, but its really not very much lighting if you plan to ride at speed in the dark. You can get a glass lens, but much more than a 70-80 watt bulb in the headlight and you're looking at a stator mod / upgrade because you'll be at the upper limit of the stock electrical system. Look here: potential output after a DC Conversion and here: KTM DC Conversion (2mb)

    Bernie's might even have the aftermarket plug and play brake light switch in stock - when I was last in there about a year ago they had an impressive supply of KTM stuff in stock.
  14. Not bad advice really. You want to be sure that the suspension is setup properly, and that you trust the bike. You'll be making a huge step up in power from an XR400, but also a better suspension too. But if you feel comfortable on the 520, why not? Just be careful, don't hurt yourself, and remember its all for fun and its a lot more fun not to end up in the hosptal. I would go with your gut-level feeling after riding the KTM a bit.

    I bought the OEM KTM brake light switch at Bernie's in Mesa, AZ while I was down in Phoenix, so you may very well find that a local dealer has the switch in stock. Had to improvise a little wiring, and I soldered and shrunk-wrapped everything for a trouble free installation, but it was easy and only took an hour or two including bleeding the rear brake.
