Yep, could possibly be loose gear lash also.

Turn the front 2 lifters one more 1/2 of a turn - try that before tarring into it

I'd hold up on the roller rocker arms until after you add a 1/2 turn to the pushrods like JonhZ suggested. And keep in mind that roller rockers aren't required until about .580-.600 lift, and, roller rockers tend to be noiser than standard rockers too. So if you are tyring to get rid of a ticking noise, roller rockers aren't likely to help.

Bike pulls great, no weird noises or knocks but has that random tinging noise. Going to drain oil and check for specs and switch back to conventional... valvoline vr1 high zinc 20w50

I have heard with some EV27 installations that the stock springs are tired enough and you are getting noise because of that..

Update... bike is silent as a sewing machine on cold start... zero noise from anywhere if i start it and take off... once warm is where the irregular tapping noise comes in. Also... changed oil back to conventional 20w50 with high zinc.
before i loose my mind... rod knock is gonna be mostly low rpm and constant? Or can it come and go...
checked run out on crank and it only has .003 thou of run out and zero end play per my dial indicator.
