    runs on choke is pointing to clogged pilot jet circuit.

    that is the pilot jets and mixture screws this is the circuit that runs the bike at idle up to 2 to 3k rpm when the main jets kick in

    Did you set the float heights? I think this can happen if the float height is set too high. Setting float height too low causes a lean condition.
