Recently found a 91 K75S w/13k miles. It’s been idle since 2008 so I’ll be chipping away at the various well documented gotta do’s. Previous owner had their local BMW shop attempt to bring it back to life with a new fuel pump & kit but a fuel leak and the rapidly escalating invoice provoked the sale. Upon receiving the bike, I put a gallon of fuel in, installed a new Westco Battery, a new Starter Relay, and gave it a whirl. To my surprise, it started immediately and purred like a K75 should. After 10 min or so I killed it as fuel was leaking out both sides of the tank. Interestingly, the starter continued to churn, so I disconnected the batt. I whacked the new starter relay and started it again and upon shutting it down, same thing…..kept chugging. So I’ll be trying to find what’s causing the relay contacts to weld, given the batt is new and fully charged and the relay is new as well. Any thoughts/ideas from the Brick Brain Trust would be appreciated.
Upon removal of the tank no obvious holes were found. The fuel appeared to be coming from the fuel sender mounting point, so now I’m in the process of replacing the corroded fuel sender and o’ring and will complete a leak check next.
