Wednesday last week, which was a warm Melbourne day (even at 1800), I ended up filtering pretty much from Warrigal road up the Monash and along Punt road. Unfortunately, when I went to turn from Wellington parade to Brunton avenue, my bike died in the arse. Didn't even have idiot lights. I vaguely recall it feeling, towards the end, a little like it was running low on fuel, despite having a full tank. After sitting around for a few hours the lights came back and a bump start did the trick; it's been running fine since and I'm not too worried about it, but I figure it's worth actually diagnosing if only for the practice. It's a 1989 VFR750F with a Motocell lithium battery. Otherwise stock for the electrics, as far as I'm aware (only had it the last few years, though). I think the coolant is about due for a change. My guess is something was affected by the heat (alternator?) and meant there was no electricity being generated, resulting in the bike running off the battery... until it ran flat (and as it got low the spark suffered, causing abnormal ignition and that 'low fuel' feelin'). After the battery had rested for a bit, there was just enough charge to light things up, but it was well short of the juice needed to turn over. Having cooled down, the other stuff was working again and therefore willing and able to do its job after getting a push. Do I sound like I'm on the right track? Am I more or less ignoring something that's screaming threats of earth-shattering kabooms?
