So yesterday after my ride, I got home and tried to unscrew my oil drain nut while the oil is hot to get all the stuff out. It is a 10mm hex nut. Because my drain nut is aluminum it is very soft when hot and somehow it was on way too tight. It wouldn't budge and I ended up rounding it.
Today, with David as lead engineer we got the tight rounded nut out!
Pic1: Rounded 10mm nut problem and plan without replacing the oil pan.
Pic2: Punching the drill hole.
Pic3: Tapped threads for machine screws.
Pic4: Space age wrench.
Pic5: NUT OUT, CARRY ON!
I feel happier than getting a new bike at the moment the nut came loose!
