Looking to pick up an ignition advancer, either the factory pro fixed or Muzzy's adjustable.

I got the Factory Pro race jet kit already, looking for an ignition advancer. Anyone know how much advance you can dial in on pump gas? I've got an '02 ZX6R. Factory Pro sells them in either 2 or 6 degree advance.

I got the Kawasaki factory service manual, funny thing is, in the owners manual they say use 91 octane, but the factory service manual says you can run 87 in places like the US and UK that have high quality fuel.

Based on the octane recommendations, I could advance the shit out of it with 94 right?

Thanks in advance (haha)
