Getting quite a list of things I have done to it since my dad gave me it a month or so ago. Brakes, oil, battery, cables, fixed headlight, fixed oil leak (only to find another, acceptance is key), ridden it a LOT, love it. Bits of fettling here and there but mostly riding and improving her.
Today, I have soaked my new fuel tap plunger thingies in petrol ready to swap tomorrow and will drain and clean tank, swap throttle cable and another bar end mirror while i am at it.
For reference, the old man had done 200 miles in 2 years on her, I have done about 500 in about 7 weeks, my KTM1290 SAS has been ridden once for about 200 miles and the 640 Duke hasn't turned a wheel! Wondering what i can buy if i sell the Duke, I have caught the bug!
