Hi There,

I'm working on restoration of an MC16. Hoping to do some minor tuning mods to get a few more HP. I note the comments on this site r.e being able to get up to 55 HP from one of these motors with "delimiting" but there is not much commentary r.e. what this de-limiting is on the MC16 vs the later models? I note comments on the tuning page r.e that performance of the mc16 is partly due to smaller carburettors though I was under the impression they are the same size as later models or am I mistaken? will fitting carbies from say a MC21 be a fairly inexpensive modification along with removing the airbox and re-jetting to suit?

Hoping to get some advice from anyone who has tuned the MC16 and has some tips. I'm not after massive HP but some good reliable power gains.

Thanks All.
