That shows the quality of proper tuning. That initial surge then on to the full power twin band hit at 6k.

Need to check your licence though. Prob above A2.

If the bikes been rebored will I need 1 and a half bands? If I cut the second band slimmer will that be OK?

you normally have to measure the width of the bands to the cc of the bore, that way the power band is resonating at the correct frequency of the engine and ensures longevity as well as power!

hope that helps
