Upon changing the coolant on my 03 650R, I noticed the end of the coolant drain bolt on the water pump looked like crap. The threads looked thin and pretty defective. I noticed in another forum someone mentioned this about their bike as well. Anyone else noticed this? Every other bolt on this bike looks fine so it would make me wonder what the deal is with the drain bolt? I was wondering if it is a sharper thread or somehting but I doubt it.
