So just a quick one.... Anyone know any reason there would be more smoke coming out of the left exhaust than the right one ?

If you are still getting pressure but no smoke I would worry that the oil feed has a problem. If there is no pressure and it is only running on one cyclinder could be anything from fuel to spark. I wouldnt run it until you make sure that its getting oil to both cyclinders.

Full details are in the manual, but basically you run bike on premix, disconnect the oil lines and measure the rate the oil is being dispensed. Relatively straightforward to do, but involves holding the bike at certain revs for a while to measure. Just check your neighbours aren't having a posh garden party before you do it (ask me how I know this..)

Cheers although I have no oil pump as its a track bike and running premix

Carbs not balanced ?
One cylinder may be running slightly higher
