I am with the consensus of opinion here that you have to ride these bikes differently. One thing that I found particularly unusual was the need to slip the clutch at low revs.

Tis a common thing to see some folk wind a throttle wide open when a bike does not start to well, my Mrs will do it on her zzr600 sometimes instead of just lifting the butterflies a little. It don't matter how many times I jump up and down shouting it just won't go in.
It may just be a habit thing. Maybe it's worth a slight change of habit
Not saying don't do it but maybe a little less. Maybe adjusting the clutch cable will allow you to feel it bite earlier so you know better when to give some throttle.
