Does anybody have a service manual for the 550 LTD that can be downloaded free!??? I´m specifically looking for carb info pertaining to the air/fuel mixture screws and what the factory had listed for the preset. I could also use some advice, I´ve stripped the bike down to its underwear, re-geared it for max accelleration, im running open exhaust, velocity stacks, stock cam and carbs, so any suggestions that would help me in the jetting and carb setting feild would be greatly appreciated.
