Hi guys, I’m about to make a purchase decision on a KTM SX-F 2013. Since I’ve only driven 2T so far and have no experience with 4T at KTM or in general I wanted to ask what you do about maintenance per hour interval etc ….. Everything that is important and so on… I’ve already read a little, here are a few things here for sure even more. *Air filter should always be perfectly clean and oiled, after each training day a new or cleaned pure (? ) *How often does the oil and the oil filter have to be changed, in the start-up phase and later. In the case of a new engine, there are more “spans” at the beginning than later (?) * Engine maintenance: this model should check the engine or the plain bearings, etc., adjust, replace (?) *Coupling (?) I only know the conventional clutch rings and the springs at the 2T *How about the valve play, how often does it have to be controlled and adjusted(?) *Gabelölwechsel (?) *Bremsfl sweetness (?) *Brems and discs is a clear thing and everywhere is the same, if below then new 🙂 *What else needs to be considered I don’t know yet, am still looking at. Read the operating instructions… I have a personal interest in dealing with the mashine properly, just always leave and let it be done is not so my thing, I prefer to put on my own hand. But what should then have on “hand and foot” and not end in a tinkering! I w w I’d be happy if you could help me! I know this is a big theme 🙂 Many greetings!
