    Exhaust intake flange SXS02540506 Where?

    I'm trying to buy this flange which I have heard gets rid of the deceleration backfire on the 525 but every site I go to they say it's not available does anyone know the exact year make and model that this comes from so I can look under microfiche and order it that way thanks in advance

    Just call Rocky Mountain, Motorsport or any KTM dealer and have them look it up in the KTM parts system. If it is still available they will tell you. If it is discontinued permanently please let us know.

    And if it is indeed unavailable, take your header and trim 1/8" off the inlet pipes. That will let the header seat up against the flange on the inside of the pipes and seal off better. Stock they just sit up against the welds on the outside and it leaves gaps to suck air in.
