Vertical cylinder carb is a sidedraft and the intake points just to the left of the headstock so in the 'firing line' of the front wheel, horizontal is a downdraft and points directly upwards under tank.
Originally I had the supplied (blue) Keihin bellmouths which doubtless work well but the only way to fit a filter is to use a foam 'sock' filter which robbed power at the top end but had to be used as the carb would be sucking in all the debris from the front tyre.
Sock filter fitted;
Since then I located some longer stacks which are less 'bellmouthed' and longer but have a thicker end that a filter can be clamped to, the (K&N) filters are much wider and so don't disrupt the flow like the sock filters and also filter better.

For old school bellmouths, I have open intakes on the Guzzi with just a large mesh to keep stones etc. out but due to the design these face backwards so are OK (as long as I don't ride it on the beach).
Cleaned up;
