new to Banshee's

[riderofthestorm]

I recently bought an 88 Banshee, and it needed completely rebuilt!,, i got it bored to 60 over, prolite wiseco pistons, new stock crank, it has DG full exhaust(on it when i bought it!) k/n filter without the snorkel and drilled fillter cover, boyeson pro series dual stage carbon fiber reeds, boost bottle,,TORS eliminated, but it doesn't have the idle kit i got the motor back and it has ngk b8es plugs,,, my current jetting is 240 main with 27.5 pilots, needle set on the 3rd setting,, how many turns out for the pilot air screw do i start with? before i put the carbs on i need to know if i should up my jetting? and are these the best plugs for my shee? also i was told the boost bottle just takes up space, doesn't actually do anything? i live in Pennsylvania and ride between 1500 and 2000 feet above sea level? anything you can help me with would be great, i just don't want to mess up my engine during break-in cause i have a lot of cash tide up in this thing thanks!
