[QUOTE="Magnetoman, post: 165879, member: 2806"] Many years ago I bought a valve with microswitch (not the one mentioned by Greg) for my Matchless G80, but the construction was so pathetically crude I never installed it. The seller offered to take it back but I kept it as a reminder why I shouldn't buy things I can make myself, because I'd never make such a piece of junk. Two of my Gold Stars came to me from the estate of a plumber so, unsurprisingly, evidence of his trade was to be found. The next photograph shows the valve he put in the oil line of the BB Gold Star. [ATTACH type="full" alt="BBGoldStarOilValve01.jpg"]54635[/ATTACH] Although my BB Gold Star has a Magdyno, so a grounding it would be easy, my first instinct was to simply remove the valve to avoid ever forgetting to open it. But, I left in in place "temporarily," mostly out of laziness, and got used to it. When I ride it regularly, opening the valve in the morning is just part of the routine, and when it will sit unused for more than a few days, I put a sign on the throttle to remind me to open the valve. [ATTACH type="full" alt="BBGoldStarOilValve02.jpg"]54636[/ATTACH] I don't know if I actually need that sign to remember to open the valve after a long layup, but I don't feel like testing that hypothesis.
