thanks for the information Joe, my lock cylinder doesn't look too beat up, so I'm hoping I won't have to get a new one, but we'll see. Is there a good method for removing the vapor barrier and, more importantly, getting it to stick again nicely? That is always the hardest part, but perhaps I am missing some secret that makes it easy.
I've been considering a kill switch on the clutch sensor, as opposed to the fuel shutdown solenoid, because at least then they wouldn't burn up my starter trying. Though some have pointed out that if it doesn't even turn over, it makes it obvious that there is a kill switch. So I thought about doing one of each and just putting them different places since neither sounds that expensive or difficult.
