How the F**k do you do it

So im holding 3/4 throttle with my right hand
I push the ignition cutout BUTTON (not switch) - Left hand
I then go for the clutch -left hand
The engine bump starts and buggers up the Chop


Ok so questions
1. Is it ok to do a plug chop with the bike stationary in neutral? (so I can use an extra pair of hands)
My guess is no coz its not under load and there is no forced air cooling (however Dynos dont have forced cooling either)
2. If 1 = NO then HOW do I do it without 3 hands
Thanks
