help with jetting for gs550, need baseline

[dentoncafe]

Im currently in the process of rejetting my carbs and need some advice on what size jets i should start out with, I have cut the ends off my exhaust but the baffles are still intact, and i have put pod filters on my carbs, I have 115's in there right now and it has a flat spot at 1/8-1/4 throttle, the idle is spotty and it dies sometimes at the light. My bike is an 81 gs550T suzuki. I have 4 carbs. I have the mixture screws set at 2 1/2 turns out. Anyone with a similar setup, could you let me know what you are running so i have a starting point to tune these darn things. thanks a bunch.

There's not a whole lot of GS550's here (sad to say), but have you checked on the GSResources? I can just about guarantee that somebody there has that bike with that setup.........
