This bike may just drive me out of BMWs. After replacing all the tank components a year ago, except the sender unit, but not riding it much since then, in recent weeks it keeps blowing the 7.5 amp fuel fuse. I tried using a 10 amp, thinking it seemed to be at startup after sitting, but it didn't help. Now the bike will stop running at any time as I ride it, just shuts off. Yes, it's a lot of fun when that happens. The fuse is always blown. Put in another fuse, it goes for a while then stops. It can't be ridden. I have tried completely disassembling and cleaning the sender unit, even re-wired it since the wires were falling apart. No luck.
I thought about trying to bypass the low fuel system in the sender and just wiring it straight through to the pump, as I read someone had done. But I suppose I will have to bite the bullet and order a $280 replacement for the little sender unit. They are not available used or aftermarket. Of course other similar units for other brands are about $75 to $150, or less. Gotta love BMW parts prices. And there's no guarantee that will fix it, which is the best part. Maybe I need to take it to a dealer and pay about $500 for a diagnosis. Then I can add on the part and get it up to about $1000 to fix the fuel fuse. Everyone raves about the durability of the K75s. Maybe that's true if you get a good one. That's my mistake.
Old or new, you need deep pockets to own one of these German machines.
