You will have to do some throttle twisting to fill the accel pump & lines, but i have a better alternative.
while the carbs are on the bench, & your just about done, have them connected by the braces, & the accel line attached. while the rear carb top is off, fill the rear bowl with gas and operate the throttle several times till the nozzles squirt.
you chould have a nice cone shaped spray, if not, use ONE STRAND of picture hanging wire to clean out the nozzles. if they are really bad you'll have to pull them off. that procedure is best explaned over the phone, so call if you need to.
also, this is the time to make sure they are alligned properly. it affects performance. they should spray between the wall of the carb & the throttle plate. if they don't, gently bend them till they do.
be sure to synq the carbs & set the pilots when the carbs are back on. hopefully you recorded the pilot settings before you pulled the carbs so the bike starts easy, or close to it.
