I am surprised that the dyno people did not tune out the carb weak / rich running as that should be pretty easy. 47 Bhp was the factory figure when new so 32 Bhp at the back wheel is not far off the 20% transmission loss gestimate! I would try a 36 mm carb with my jetting on the carb page on the website and see how that compares.
Also what filter do you have I found Ram Air foam filters gave much better results than the cone type.
I was thinking of Port tuning as some later bikes had the Peter Green porting, you will have standard port timing unless tuned but by the sounds of it not.
