I just replaced the clutch and got it all closed up. It started and ran on the table before I took it all apart. Fuel pump and injectors seem to be doing their jobs. Turns over strong. No spark to be had. The coils seem to check out (~10k ohms) The coils seem to be getting power (~12v) and they seem to be getting signal when the engine is cranking. New plugs haven't helped. I doubt I managed to bugger up all 3 plug wires at the same time, but I guess it could have happened:huh I put dielectric grease on all electrical connections on reassembly. Is it possible for this to cause problems? I'm thinking I might have managed to somehow kill the EFI brain or one of its wires, but I don't think it talks much with the ECU that controls spark. And I never touched the ECU box. Any ideas? I'll buy the beer if you can bring over your K75 so I can swap and check parts. EDIT: I didn't replace the "guardian bell" that the PO had left attached to the bike. Will that cure my problems?
