There's one in this Bonneville car, too. It's bored to 1500cc with the staggered cylinders, 11:1 CR, runs on both gas and nitrous. It's gone over 248 MPH in this little lakester! They've held the record class for 14 of the last 17 years with this car: it started with a 750 SOHC4, became a KZ1000 (bored/stroked to 1200), then the 'busa. Last I heard, they are fitting it with a blower for next year.
I worked with these guys for 14 years, great bunch of folks!
The donor bike for the original engine became the one on the cover of my book (but with a different engine).
