MOB - is this being done with carbs on the bench. thx
yes, this is how I statically set the bank after a rebuild and cleaning prior to install.
If you sucessfully cleaned and set the carb floats correctly, this step will amaze you when you install and start the bike. it should be so close that when you put the synch gages on you will likely not need to do more than set a screwdriver on the synch screw to make an adjustment..and have to think long and hard whether you really need to turn the screwdriver.....in otherwords, it will provide a synch that is almost perfect from the start....
that is, if you have your valves all adjusted also.....if they are out of adjustment, it will show up as a synch being needed
based on the valve differences/errors.
