SUCCESS!!! I cleaned carbs again and blew every hole I could get to with compressed air. So I have new needles and jets, new main jets (92.5 and 95), new float valves, new pilot jets and mix jets out 2.5 turns. Put all back together, fitted without air box, filled float bowls with fuel via a tube and funnel, checked fuel out from pump (slow dribble), set choke 3/4 and pressed starter. Immediate start! I can’t get the grin off my face!! Bike seems to rev OK but I’m not pushing it as haven’t changed the oil yet. All I need now is to get the air box back on! It’s time someone designed and made a new one that can be fitted after carbs. Come on engineers, someone make one! Thank you so much, Marcel, for all your help. I tried to load a sound file of engine running but it wouldn’t load. Boo-Hoo!
