The engine came from a written-off bike that had been dropped, there is a scrape on one end cover as can be seen in the photos. The engine was my spare from when I was racing but I never needed to use it. The exhaust, wring etc all came from my GTR when I stripped it.
It is currently setup on a test rig and you are welcome to come and see it running, in a properly Covid secure way of course.
Price for the whole thing as seen in the photos £2,200.
