I might have missed it, but how long until you turn 18? FYI the exc seemed to undergo lots of changes over the years just like the other ktms did. I have seen guys who control the throttle hand get some really long intervals between piston changes on their two strokes. It is kind of a narrow band so to speak, not lugging the engine (going too slow for conditions) and not over reving it (having the engine at an RPM that is higher than it should be). both can cause over heating and premature wear.
I woudnt want the 4 stroke either for your useage(s).
