I'm running a liquid-cooled Malossi 221 with a Vespatronic ignition and on my last couple of rides I've had trouble with overheating.
I've traced the problem back to the battery going flat!
I'm running a constant-rated water-pump (I'm running twin radiators behind the legshields, so the pump's always running) and an electronic fuel pump - both of which are drawing very slightly over 2 amps combined.
I've checked that the charging circuit is working (it is), but I don't know what the current into the battery is.
I can try a bigger battery, but if I'm taking out more than I put in it's just delaying the inevitable.
It's a gel-battery so I'm also a bit in the dark about charge and discharge rates.
Has anyone got any ideas about what current the Vespatronic charging circuit can supply???
