I had the 750 Paso a few years back. Spent more time fixing it than riding it. Was a pig of a thing that had been swapped from the Webber carb to twin Dellorto's. Didn't realise for months that only one carb was connected to the choke so when you pulled the choke on, it only worked on one carb and would not start or stalled out continually. Also if left parked for anytime it would leak fuel through the cylinders and fill up the sump. Rode it to a mechanic one day and he said I was lucky not to have blown the motor apart as sump was full of fuel. I believe the 907 was a more superior bike as Ducati fixed all the problems that the 750 had.
