Kev,
I know a bloke who makes rearsets & crash bobbins for the ZXR400, they are the ones that Race Products & a lot of the Paddock sales vans sell, can get them for you inc P&P for £95 for the rear sets & £30 for the crash bobbins, do both together & i will sort it for £120.
Shaun Webster is definaitly the guy for the tuning, he will advise what is needed & will then do what you want.
His engines are well reliable, will end the season with the same bhp as started.
For fairings give Dave a ring at H C Racetech, all mounting points fully reinforced with carbon, 01522 702800
Chris.
