You did not specify what year, a 08 KTM 65 SX requires .5L 2002 sx65 to a 2008 sx65 according to my service manual only uses 300ml of gearbox oil. 2009 to 2011 uses 500ml of gearbox oil.
ktm 65's are pretty much as good as you cant get when there stock, although you cold adjust the jets a bit and get suspension upgrade. the ktm exhaust pipe is the best some say although fmf do a slightley thinker versionn as sometimes stones pentrate the stock pipe. butthe again some say a hgs exhaust or such like fmf or pro circuit.
