Re: Can a 600 Spit Blue Flames?
The BMW up there has a quick shifter - cuts ignition and injection for a fraction of a second to unload the transmission so you can upshift without using the clutch. That may cause unburnt fuel to be blown into the exhaust where it ignites and makes that flame.
It's not mapped poorly - considering that particular bike finished 2nd in the World Endurance Championship this year...
