should cool down the engine with 1-2 minutes idle before kill the ignition
I treat the H2 as my Legacy(turbo), idle for some minutes before switch it offI have not heard that this is as much of an issue as with a turbocharged bike. Since you do not have the exhaust superheating things, temps are much more manageable. Plus, this guy never got it that warm.
The rider is Philippe Monneret, a famous rider here (in France) who won 24h du mans It's only for his pleasure and his TV show. It's not for Kawasaki because he always like before Yamaha (his sponsor when he rided)
