ZX12R, Flat spot around 2500 rpms

[Roadeta]

Hi all,
Just fitted a full Muzzy system to my 12, then loaded a Muzzy map on the PC111.
She idles rough and has a bad flat spot around 2500 rpm,
Anybody have any ideas?

Yep that's Muzzy for ya.

You should get it dyno'd they'll be able to smooth it out a bit, also adding one of these works better than an electronic ignition box for the flat-spot, but you'll never eliminate it completely.

Them things need revs. Keep it above 8000rpm at all times

Big Guy put a Muzzy on his 12 had the same problem, he fixed it buy buying a ZRX
