Hi,
So David Vizard recommends the following.
Main jet: 145
Air jet: 180
Em Tube: F16
pump Jet: 45
idle 50F2.
This is for a Standard motor with modified head.
Id say to start with you're main is WAY too small in relation to your air jet. If you can, get a set of jet drills and start off with a 130 and drive it and see how it goes, each time drilling very little out till you're happy.
Whats the rest of the engine like? any porting done on the head? If none is done you're not getting full potential from your cam as a cam with a standard head will keep you back a bit.
Question though, what is a DY5 cam?
