I'm quite new to these bikes, my MC28 SP has decent MMax pipes, and I assume it has been derestricted as it's quite nippy . This is how my engine runs:
Around 6 - 7,000 rpm the power starts to pick up noticeably, then at ~ 9,000 rpm there is a strong pick up in engine power, which drives hard until it levels off at around 11,000 rpm, though the engine will continue to rev to 12,000 rpm (not sure how much further it would go), the power levels off and is feels quite flat after 11,000 rpm.

As NSRMonkey says, it should be quite rev hungry and spin up quite fast beyond 7,000rpm. Try giving it the berries and see wot happens!
