I had some more time trapped in the shop due to rain and decided to finally do something about that hole in the frame behind the carbs. Ginned up an aluminum plug with an o-ring to hole it in place. It just pops right in the hole. Spot bored the face of it to fit a 1 1/4 diameter union jack that I cut out of some decals I got from fasteddy a while back.
