zx636 transmissions

Hey I just bought an 05 636, No probs so far but I have been reading about transmission problems (popping out of 2nd and 3rd gear) mainly in american forums. I was wondering how many of you have experienced theses sort of problems? I had an 06 zx10 about a year ago and I mainly did clutchless upshifts (did for 15 000 kms with no probs when i sold it), Im not too sure now if i should be doing this if these transmissions are so weak. The shifts feel smoother on the 636 without the clutch aswell....Any opinions?

Positive gear shifts my Z750 jumped out more than the 636 but if you make positive changes & don't get lazy you should have nothing to worry about.
Edit, I do clutchless changes all the time, spose you just get used to it
