Ok guys well I have no idea where to be starting from hence my question!

The carbs had 180 mains and it was rough as arses even on the bench.

The standard carbs had 110's in, no idea whats standard on an mc18.

So any rough idea of where to start from? I dont want to have to buy ten sets of main jets, got tons for mikuni's but nothing really for keihin;s.
