You might want to try cracking the float bowl drain screws, to verify each float bowl is filling properly.

Are both coils producing a spark ?

Hey Wookie!! I am assuming I am getting spark since sometimes it seems to fire up fine and can tell by the sound when all four are firing, not to mention the down pipes are all hot. I mean I suppose the coil could have an intermittent issue? When it does start up correctly it sounds so good with the 4 in 1 exhaust. As I side note I found that the gas tank is leaking at the fuel level switch.

Try laying the leads for #1 & #2 (one from each coil) on top of the cam cover with a spark plug in them and crank the motor you should see an equal spark on each plug (I appreciate this doesn't guarantee it's sparking in the cylinder under pressure but it's a "quick and dirty" test)

What is the voltage at the coils during cranking and when running (check both) plugs will spot if it’s only been running on choke

Assuming I did it right I am getting about 11.3v on each coil. At the battery I am at about 12.3v.

You should be putting the red meter lead on the coil supply (normally either red or yellow/red) and the black lead on the battery ground - if that's what you did you either need to find where you are losing voltage or fit a by-pass relay (there are several threads on that topic here on the forum)

Yup, that's exactly what i did. Used the ground terminal on the battery as well. I would also note that the voltage of the battery also dropped when I switched the key to start. With the key off the battery returned back to its nominal voltage.
