You need to look at the post history of that 1995 Monster-T guy. that guy is advising everyone here (so also many racers) to use 18% oil and roto/pullstarts that can up with huge discussions as if we all are stupid and he knows it all because all his 50 engines are still alive and running fine.
His advise to use a rotostart is basically based on getting a backplate rotostart because he does not know better but yes, as you showed on the clutch side it is also possible to start with a some kind of electric motor.
