You'll have to have the barrels turned down or have the case bored out to use the G5/SP1000 units. Those are cast iron barrels. Probably need a hone and new rings at the very least

MG cycle, Harpers Moto Guzzi, Moto International, etc sell new Gilardoni barrels and pistons rings etc. as a kit.

 I'd go that route.

you also can get cyls with the 1000 bore but fit 850 cyl holes
