I have a set of Dellorto PHM 40mm carbs for sale. They were taken off my 1980 Darmah, although I'm pretty sure they weren't the original carbs. I swapped them as I was struggling to get the bike to tick-over, but new carbs made zero difference as it turned out to be an issue with the plugs - expensive lesson! They're well used but in good, clean order with all new seals etc. Anyone interested, PM my and I can send you some pics. I'm open to offers.
