I've got a Morgan Carbtune and it was supplied with plastic adaptors in both 5mm and 6mm.
 
I bought the brass adaptors for both my Ducatis as I leave them permanently in place due to being hard to access (rear cylinder on the 916 is completely obscured behind the airbox, so I leave a short length of hose attached also) but on the Guzzi I use the plastic adaptors because they are easy to get at and I don't want to leave adaptors permanently fitted as they would be prone to breaking and just look ugly due to being on show.
 
Anyway the Morgan stuff is good quality and reasonably priced and I have found their customer service to be top-notch.   Thumbs Up

On a twin, to balance carbs or throttle bodies, all you actually want to know is the relative vacuum between the manifolds.
That's why I first of all used a manometer, very cheap to make and far more accurate than any carb tune device. (Details in the FAQ section).
I now have an electronic version of the manometer, the Twinmax.

The Morgan Carbtune is a mechanical rod manometer.
They work very well.
Use them on the M900, Le Mans and the Double Twin-Choke Spider fr balancing.
Le Mans thing (plus other stuff)

The difference is that the Morgan shows individual vacuum for each pot whereas the manometer I mentioned, plus the Twinmax shows the difference in vacuum between the posts, which is all you actually need to know. It is thus more accurate.
Where you are measuring in millimetres on the Morgan, the manometer would show inches.

Carbmate (the One I have) actually works on the same principale (the differenze). It's less fun than seeing the columns go up and down, but it makes it pretty accurate...
