Yea, I rebuilt this after laying it down a couple years ago. Bored and stroked - it was sick, absolutely sick. 148MPH is as far as I dared and I still had a handful left. That engine is what put Honda on the race circuit map. SOHC. They completely fucked it up in 78 when they came out with the DOHC. The same 78 bike couldn't touch the 77's.
