Hello again. Have you checked that the vacuum readings on all four carbs are the same ? No leaks ANYWHERE ????  All the jets are ib the right place - on other words you haven`t mixed up the primary with the secondary jets?. The float level should be 15.5mm (0.61") the Primary Jet is 68 and the secondary jet is 102 - thats from the Honda factory workshop manual that I have  What RPM are you doing at say 100KMH /60 mph ?? Also check the number of teeth on the rear sprocket. Front should be 15 and rear anything from 38-44. I know my Honda on long distance touring trips gives me 42-44 MPG , but never bothered to check when running around the city. Idle speed is 1000 rpm +/- 50 rpm
