Han fastnade väl i grappaberoende, eller ?
Nä, men här är iaf. en liten intervju med honom:

""All you will have to do to release 128 bhp from the standard bike is to remove the airbox, change the exhaust, and fit a new chip." . . . .
"Later, when asked why he had not opted for a chain drive, at least on the racer, John explained that Guzzi's research indicated that chains, while satisfactory in terms of efficiency when new, lose efficiency in the first thirty minutes ( of continual loading ) from a starting point of 8% down to 20% . While this was acceptable in short circuit racing it was disastrous in his preferred formula, endurance racing. Conversly although shafts are responsible for a relativly high initial loss of power (about 12% - depending on the design) they maintain the same level of efficiency, more or less regardless of condition.
In John's opinion the only tangible disadvantage of a chain over a shaft is that of unsprung weight."
