Obey Torque loading.......... (Drain Oil Nut)

When I started doing my own EO change. I tot I could save some money in the long run on buying EO from dealers and saving on labour. Little did I realise I had to spend a bomb due to a silly mistake...........

Since I was an Aircraft Technician, I tot torque loading applies to aircraft since its such a critical piece of kite...... (Read somewhere: taking off speed for F5 Fighter plane is close to 290km/hr) My Busa can run faster.....

I started changing my EO last year, always tightening the bolt as tight as I could, coz I was always afraid of it loosening during those insane speed...... Little did I know I was damaging the thread more. My last EO change was the trial "Royal Purple" that I wanted to gives some reviews.

A week after that"Royal Purple" EO change, oil started dripping from the drain bolt. It was always wet whenever I wipe it and tighten somemore(big mistake), after 2 attempts, I knew something was very wrong and I brought it to the bike shop. The mechanic told me either the bolt thread is gone, or the oil pan drain sum thread is gone. We discussed and decided to drain it out to take a look at the bolt's thread ............................................ removed and inspect .................................... it was 'OK' Which means I have to replace the more expensive one . Itchy backside me.....
