I have a few wildly different questions, and I'll put them up at once instead of clogging the board with three different threads:
1. The factory tire size for my bike is 3-inch on front and 3.5-inch on the rear. Would going to a 3.25" front and 3.60" rear make a big difference? How would the combo of a 3.60 K81/TT100 on the rear and a 3.25 Avon Speedmaster Rib up front be? I would go with K81s at each end, but can't find an 18" narrow enough for the front. How would 3.60 K81 up front with a 4.10 K81 at the rear be? I want to be as close to correct (regarding handling and feel) as I can.
2. How do clip-ons get that down-turned angle? It seems that when they are on the forks, even if they are sloped back, they would still not get that "clubman-style" downturn to them, and would stay kinda parallel to the ground. I know some clipons are wildly adjustable, but I don't like the look of them and am wondering if "regular" clip-ons can get that downturned look.
3. DSS sells modern repro sidecovers for my bike (400F). They are matte black and being that I have a '76 all I would have to do is spray a gloss clearcoat on them and they would look correct. They aren't that expensive and are reportedly made of better plastics than the originals. Should I pick up a set to use and preserve the originals?
