Clutchless changes

[Distant]

I passed my DAS a couple of months ago and got myself a zx6r within a couple of weeks. Now I've been pottering around and steadily building up my confidence and am now happy giving it the beans, in a straight line at least...(Still crap on the corners though)

I was chatting to a mate the other day and he informs me "everyone" does clutchless changes up the box when giving it some. How many people do this and will it destroy my gearbox/clutch?

Cheers

Thanks for all the responses guys. It seems as though this is the norm and I'll be trying a few changes up the box without the clutch next time I'm out for a blat.
