Do you have the ARCS (Automatic Return Choke System) where you move the choke lever to CLOSED and it slowly opens on its own?

See the attached .PDF file that has detailed troubleshooting and adjustment procedures to tweak/tune the ARCS for correct operation.

--Sometimes, the flywheel brake lever cable might required inspection/adjustment, and the choke rod may need to be bent slightly to achieve correct gap/spacing.

--The air cleaner case may require slight trimming of a plastic edge to prevent binding against the ARCS cam assembly. A cylinder barrel cooling fin may also require slight filing to provide clearance.

--More tension force from the return spring is available if one tip is repositioned.

All the above and more is detailed in the attached document. Hope it helps!

Caveat: I work for Honda, but the preceding is my opinion alone.
