Hi Guys

Wondered if anyone can offer some advice? I have a 1987 MC16 Engine. I was informed that putting on the MC18 barrels and heads on have a better porting system. However recently discovering that MC18 and 16 have a different carb set up as mc16 are 28mm and 18s are 32mm can I jet to suit? or should I change carbs? Also will the original cans for mc16 fit the 18 barrels. I am quite enjoying the work and getting the experience but am beginning to think I should just go back to the mc16 heads and keep the carbs as this is much easier.

Any advice is appreciated.

Thanks

Ian
