Hi all, I have just set up in business at www.harpers-ultrasonic.com, I have an 18 year non-stop ownership track record with ZXR750s and currently own a '92 ZXR750R, '94 ZXR750R and '93 ZXR750. The latter is being modded as a track bike with an ex superbike motor and will be closer to 750R kit spec when finished. I can rebuild CVKs and FCRs with genuine or pattern parts at trade prices and refurbish or respace carbs as needed. The '94 bike's flats slides have just been through my rebuild process and can be seen on the business website, I am tidying the whole bike, which was bought as a scruffy track day hack.
