Hi there, just bought a vfr800fi, loving it but having a little problem. when I leave the lights on it won't start and has all the symtoms of what sounds like a flat battery, if I switch off the lights and give it 5 mins, it starts again, I've check the r/r and the amps with a volt metre and everything is correct. Any ideas on how it could be fixed? Any Help would be very much appreciated! Cheers guys Adrian
