    There's a tensioner on the cylinder, that's a known failure point. Good chance that spring and/or tensioner assembly failed and the timing chain likely jumped a tooth.

    Could be a lot of things. Whatever it is, the motor's coming out to fix it.

    [QUOTE = "SnowMule, publicación: 42708091, miembro: 132314"] Hay un tensor en el cilindro, ese es un punto de falla conocido. Es muy probable que el resorte y / o el tensor fallaran y la cadena de distribución probablemente saltara un diente.

    Pueden ser muchas cosas. Sea lo que sea, el motor está saliendo para arreglarlo. [/ QUOTE]
    Todo el motor es nuevo, creo que la junta de la culata es más pequeña y por eso golpea la culata.

    Two things;
    The bike looks totally sweet, and your chain looks way tight!

    My bike was sprung pretty close to my weight when I bought it, but I’ll be curious to hear what’s being done to yours and how you like it when it come back.

    Owner of Suspension 101. Read a ton about him on forums and comes highly recommended.

    George bent over backwards (along with backflips) for me for doing both my 640A and 950A suspension. He also installed his Gobblers in both of my bike's forks. My 640 now just kills it in the desert. Last year at the LAB2V it was just soaking up the 3' to 4' airs over some of the jumps out there. It was also amazing at low speeds in the super slow rocky areas as well. I visited his shop last year and he was trying to convince me to have him work on my 525's suspension as well. The problem is that he did TOO good of a job on my other bikes, so i don't ride my 525 as much as i should! At some point i'll get around to sorting out my 525's suspension with him. George is passionate about the work he does, and he's also an all around top notch good guy as well.

    Quick question for the group. I have read that RFS motors, and maybe the 525 exc in general, are having replacement parts issues. Is that accurate and does that change the potential for this model to be an adventure bike?

    Main component that is no longer available is the countershaft, so if the sprocket splines wear / strip you will struggle. In saying that, there is a guy in AUS. making a batch.
    If you want to give the tranny an easier time you can fit a cush drive rear wheel from an old LC4. I did this earlier this year, and it swaps straight in.
    There may be a few other parts that are becoming scarce, but between the used market & aftermarket we are pretty well covered.

    Whilst some KTM parts have become obsolete it's far outweighed by the amount of spares that are still easily available. Off the top of my head the following are no longer available from KTM for the RFS
    Countershaft and at least one of the gears, exhaust header and manifold for the 250, large tank, both parts rear mudguard/fender pre 2004, rear subframes, there must be more but those are parts that I've wanted.
