A mulitude of reminders here of the problems faced by late 20th.Century FF builders - when we were all too dumb to use vapourware to promote our innovative talents and had to actually build vehicles...

See the infamous Difazio speedo drive 'solution', a pulley (visible at 10'o clock through the wheel spokes), driven by a rubber band off the hub. This is why the Banana almost never had a speedo. And the innovative postioning of the expansion tank where the rider will be the first to know when it boils over. FJ, as 002, had a similar positioning, inside the bodywork, allowing me to rapidly discover exactly when the stock water pump drive went into cavitation and flash boiled the water in the head - we ran the smaller 750 drive pulley on all subsequent Voyagers (that also drive the speedo off the gearbox). Then there's the 'chain run' issue, alleviated here with a long swing-arm. although the 450 Ducati FF I built (001), that closely resembles this layout, used a 'jocky sprocket' on the Swing arm spindle and a short centre chain. If the chain sprockets had been accurate this would have given constant chain tension...

As a single seater this sort of conversion is quite attractive, providing lightning fast reactions, low wieght and excellent fuel consumption.
