Another easy jetting question was created by GregZ
Just finished complete top end on 73 Z1 motor. New guides ,seals complete valve job. Cyl. got minor hone new rings.
Stock 73 carbs 112.5 mains,20 pilots, 3 clip and Stock airbox.
Only change from stock is either a 4-1 yoshimura with baffle or a new Kerker.
Once everything is together I don't want to mess with anything
Should I richin the main jet one to 115? or 117.5?
thanks in advance

I could be wrong here but I am of the understanding that for each mod (pipe,pods, etc) go up 2 sizes for a ballpark starting point.

1 size up should be ok, but 2 might be required depending on some conditions. You will have to swap them and see...
You will have to add some more fuel to the pilot circuit however (via air/fuel screws), to prevent popping on decel.
Cheers.
