I don't think so, Kev. Not unless it's the Dyna for dual pickups that can be adjusted separately. But I don't have any experience trying to do that. You might get a hold of Dyna and ask them.
The BMWs have one ignition circuit that fires both spark plugs every time. Each cylinder fires on the exhaust stroke and that's why it's called a wasted spark system.
The Guzzis have to have two ignition systems fired independently. So you'd either need two Dyna units or one designed to handle two separate circuits.
