hi everyone, was wondering if there is a manual for my nc23 Aero out there have looked everywhere but can't find one. There is a Haynes that covers 1988 onward but says it does not cover the Aero ? Is there that much difference between the two years or could I use the settings etc from the 1988 model ? thank you in advance, barry

There is a lot of differences the 86/87 aero uses adjustable rocker arms, the 88-90 usses bucket and shim, the valves, springs head, are all different, so is the frame, and plastics ect...

I have a 86 aero in search of a manual too:)

The closest match is the identical, but larger cbr600f motor
