on the domes i think david at noss cut the domes to jims specs, but jim would know and could tell us....with the pj34's ,50 piliot 172 and up on the mains, needles in the center position, boss intake, delta 2's and a single K&N, my bike cooks, im glad i didnt go 35's and twin filters.....ive posted my intake setup tons, jim sent 3.5 inch boots for my air box to carb, i cut them to 1.5 and whacked out my tool box to scoot the air box back, i ride in the hot ass dusty desert so i couldnt see losing my box altogether not to mention one of those little single pods falling off, i also have good fat gas lines and drilled out my petcock for better flow, heres a few pics
