After seeing a second bike lose it's oil plug (one happened on the Port Mann bridge and he almost lost it @100 klicks!!)I decided to safety wire mine up--One problem my plug is hollow. I drilled a hole in the center of a frost plug then silver soldered it on the oil plug, then drilled the holes for the wire. I added some lightening holes to sex it up. The first pic. is them fresh out of the acid bath to strip off the galvinizing.
