The MC21 carbs will probably be the best place to start! You will however, need the MC21 inlet manifold/boost bottle too.

The dinky 28mm MC16 carbs aren't worth their weight, so the larger MC21 juicers are a natural upgrade.

I think the MC18 Mk1 (R2J/R4J) flywheel is a goer (don't quote me on it though!), and will give a few more degrees of advance to the ignition if that's the case.

See if you can get an old set of MC18 race pipes and then modify them to fit the '16 chassis - it's what I'd do. Well, it's nearly what I'd do, but I won't drop Jeff350LC in it again like last time... oops! :oops:

Biggest benefit to the MC16 will be in the chassis department though. A set of later forks from an MC18SP or MC21/28 SE/SP will do the trick up front (complete with wheel and brakes, of course) and then a tweak on the rear end... maybe just a rebuilt/resprung shock if the funds don't allow.
