Mixture screws

Post by Mxdeano » Wed Aug 29, 2018 2:07 pm

Hi there , could someone clarify this for me , I stripped and cleaned my carbs an had a look at mixture screws I noticed that from cylinder 1-4 was like so 2 turns out ..2turns out ..2 1/2 turns out .. 2 3/4 turns out I found this to be strange but maybe I’m wrong ?? Bike is boggy at 4-5 k but fine to redline after that , needs throttle to start ,, will start without throttle but very hastily, micron stainless steel exhaust, stock air , main jet 95 pilot 35 , any suggestions please and thanks 2003 L9

Clean the carbs & Set the screws to stock settings. See if it’s better or worse.

Could need the needle height changed
