I have a 2001 F4i. Store it for the winter. Snow melts I go pull the battery, charge, put back in the bike and start it up. Didn't have a lot of time and there is still some snow around (end of April!!). Go back a few weeks later but battery is a little low so I pull and charge again. Put it back in and this time it just cranks and doesn't fire. No fuses in fuse block are blown and I get not FI light code flashes. What did I do? Please don't tell me I've blown the ECU!! Anyone have any ideas?
