Should actually measure pilot jets, might have been hogged out by PO with drill bit. And idle mixture screws. There was one recent case where bike started and ran even with screws fully tightened! For now, tightening up screws by 1/4-1/2 turn should allow proper idle-mixtures and allow choke to work.

Although valve-clearances should be spot-on 1st, otherwise he'll be chasing phantom issues in circles forever.
