Hi Dave,
I don't really have a clue myself, but the instructor at a Katana Flying
School tells me that they have
ignition problems on very hot days. They use the bog standard 912, and they
say that the Ducati
ignition module tends to get too hot being right on top of the engine. They
would like to move
that box onto the firewall, but have their hands tied because it is a
certified engine.
Cheers, Karl
