did you find them to be very far off? You'll have to give the final report on what you've found with all the maintenance you've done and how it's all panned out when you get out and ride it.
Good job on the valves, but you guys screwed up the synch operation ! Never remove the airbox base from the carbs unless you need to remove a single carb from the set or replace fuel tube O-rings, NEVER ! Without the base plate tying the carbs rigidly together they can move around slightly ...and that WILL effect the synch. As soon as the airbox is replaced, synch will change. It's a PIA, but access to the synch screws is from underneath between the "V" I Don't think you followed directions in the service manual or you would have done it properly ......without removing airbox.
