Jetting question.

[Boogieman]

Hi,

live got a slabby with an 1127 engine in it. It has slabby exhaust and carbs/air box. 

I've managed to source a freer flowing 4-1 exhaust and a set of 36mm CV's from a GSXF750. 

I'm looking at fitting the exhaust and running velocity stacks with ram air foam filters. 

 

What I want to know is- what size main jet is a good start for this setup?

cheers
