    Only if your state doesn’t allow dirt to street conversions

    Nope, CO doesn't care. It’s already registered here.

    Are there many/any differences I need to consider? Is the “w” gearbox sufficient for dual sporting to the trailhead?

    500 EXC and XC-W gearboxes are the same.
    It's not like the two strokes with XC vs XC-W.

    I’m at 150 hours with 5000 miles and checked valves at 120 and they were good. I looked at the manual and it basically says rebuild it. What should I do to the bike to keep her happy and my mind at ease?

    I am regular with oil and air filters.

    Ran a few races but I’d say I’m not overly hard on the motor.

    Start at about 3:30 and Jimmy Lewis will give his take on it. He says he's got four 500's.

    Get a leak-down tester so you can keep an eye on compression. Then, absent any problems plan on new rings or rings+piston+valve seats every 400 hrs.
    YMMV

    Ok so pretty much leave her alone unless something changes. Got it! Thanks.
    I plan on checking (replacing if I’m in there) the clutch dampeners and give it a good detailed cleaning, fastener check, and lube.

    I must have missed something or didn't go back far enough. What is the bike doing that the manual says "rebuild it" but others say leave it alone??

    I have well over 8000 on mine. It runs like a banshee and burns no oil.

    MX season started down here in Florida at my broski’s farm. It’s an old guys track and although not my jam, I appreciate the time behind bars. 2012 exc 500. Still pulling strong!

    @Colemanfu always enjoy those! That first case over the large table made me cringe.

    I need to get brave and ride some more moto or maybe not, Haha, my local track War Eagle MX is having its first night ride tonight. Maybe I need to ride over there.

    Had some seeping oil from the right side case gasket. Have new gasket, what are the torque settings for water pump shaft, water pump cover and right side case bolts?

    Thanks everyone!!

    Starter button is dirty.
    you can take it apart and clean it or wash it out with water.
    The starter will last about a thousand hours before you need to change the brushes.
    The kickstarter is your backup.

    I have over a thousand hours on my 2012 so it seems pretty reliable. It's starting to burn oil so I am going to put on a new cylinder and piston. The valves seem to be fine but I will change the valve seals and springs while it's apart.

    I've been on my new to me 2016 500exc for a few months now and have never heard the fan come on and I've ridden in very hot weather and some technical terrain where it seams it should have come on. This is the first dirt bike I've ever had that has a fan so I'm not up to speed on how to start looking for where the problem might be. An specific pointers would be appreciated.

    I lost a key off my carabiner. The plastic little lock broke off. Anyone know the hardware store equivalent? I called KTM and they are months away from a blank.

    I have the original and card so just going to cut a few.

    The one on my 2015 comes on a lot. Last year I had an electrical problem which prevented it from coming on. I was riding tight trails and the bike overheated. There was steam all around me.

    So maybe if the bike isn't overheating, you are just not riding stuff that would make the fan come on. Mine won't come on riding medium dirt roads unless there is a long, steep, slow section.

    Just rode Lockhart Basin on a 90 plus day with 2 friends on 500's and both their fans were coming on. I've also rode some tough single track in Taylor Park, CO and it never came on. All that said, I have never had it overheat to the point of steaming like I do all the time on my 200 XC-W. Maybe I'm just riding it like a girlyman:lol2

    My 16 the fan comes on often when things slow down and gets technical, but not if I can keep some speed going in technical terrain.
