Carb Air Flow

[Bilko]

A friend is running a big carb on a standard too with an expansion.

I know the carb is big, but he's happy with how it runs.

It's a Serveta and has the louvred toolbox door, is a RAM Air filter better or the hose to the toolbox?

How big is BIG Robert
Gotta think the Ram Air would be a lot better than the current Servetta original setup

30mm I was going to give him a 26mm Dellorto, but he's happy with his set up for now. He doesn't do too many miles. (especially at the moment)!

He preferred the carb hose through the toolbox, but wasn't sure. I've no experience of this Servetta set up. I did suggest that standard might have been ok, but this might not be enough.

Much depends upon the carburettor.

I have often stated my views on carburation & I'm glad to say, not all of us follow the herd!

In fact, against my advice( ) a mate still in a time warp from ownership in the 70's bought a 34 mm PWK for his return 'to the fold'

Amazingly, I could tell from the video clip he sent me of it's first run, just how good the engine was. Subsequently, once I'd got my grubby mits upon it, we proved just how well these carbs run with adequate air filtration, with absolutely no hint of flooding, or hot starting problems.

That precise carb, following my blue printing having been gifted it (my mate elected to go down to a 30 mm PWK out of intrigue) now sits temporarily on a TS 70mm x 60 mm & the performance is awesome yet extremely civilised. Again, with adequate filtration fitted.

Thank you.
