Unless you want to do a proper restoration job, then junk all the MC16 running gear (if it's not in really good condition) and go looking for MC18 R2J and MC21 bits as 2Smoke has already suggested. As much as I love MC16's, the stock equipment is garbage unless you want a concours bike.

The problem with an MC18/MC21 front-end is that the clipons will pinch your thumbs on full lock, especially the on the right where there's a large 2T remote reservoir, but the forks (especially MC21 SE/SP ones) are leagues ahead of the MC16 items and you also have the benefit of significantly better brakes.

A Mk1 MC18 swingarm is the way to go, as it's a very easy fit and you don't need to worry about shock linkages and geometry like you do with an MC21 GullArm. The MC16 rear caliper and hanger will swap over, or you can use the better MC18 setup. An R5K 18" wheel makes sense as it's the same width as an MC21 wheel, it keeps the geometry sound, and good 18" tyres will be available as long as VFR400's are around and popular!!

MC18 barrels & heads, carbs, and exhausts are all huge upgrades for the MC16. Although they may not deliver 62~63hp like they do on a delimited MC18, they will still push a '16 into the (very) high 50's if carefully set up. Electronics are likely to be the most limiting factor, plus the standard crankcases on the '16 leave a lot to be desired. You can't (easily) fit later cases, but if you buy some and take a look inside you will soon see how to improve the early ones and make up those few extra horses.
