Well you do need some form of air filter for road use but you do not have much room around that front TB. How about some form of air box with a pipe to the filter as on the Elan. You sould not have anything too near to the end of the trumpets as it affects the power at at high rpm. My air box is too near the trumpet on no4 pot.
The air box could be mounted back to front. Pic just for some ideas.
Cheers John.

Looking at your set up is of interest as the 4/4 is running a Lotus Twin Cam. The trumpets in your picture look quite a bit smaller in diameter and this is something else I am looking at to try and make more room. It also opens up more options for the gauze filters.
I don’t think an air box would fit without some major surgery to the wings and bonnet, which I don’t want to do.
