Welcome Andy. I too was disappointed with the leaking hood and sidescreens. But you will sort it. There are many threads on here discussing the subject, but I went for Dave W's recommendation of a 3mm neoprene strip on hood where is meets the header rail to avoid the shower on the forehead. And then Allon White sidescreen inner panels (a bargain addition IMHO) which stop most of the jets from the side. And finally a bit more neoprene on the back inside edge of the lower part of the sidescreen to keep the elbows dry. We carry a couple of mini camping towels to wipe any drips, but were are just about weatherproof now. We did have rain coming through the hood stitching once, but that was in an ungodly thunderstorm in central Europe where we had to stop and park up as you couldn't see the road ahead!
Cheers
Nick
