after rotating your photos im thinking those are not s bars... or you have them way too high like timtiorler noted...
the whole thing in this motobrickers opinion is the angle of the wrists... caint make sit up ergos lean forward and caint make lean forward ergos sit up as well as the oem motogeometry... some can... most caint...
if you are sit up like the rt or the lt then the high bar are good because your wrists and in natural alignment with the high grips...
if you are lean forward like the rs or the s... the bars gotta be down as far as they can go before your banjo hits the tank... then the angle of your wrists in in natural alignment with the grips... factor in weight over the pegs... ball of the foot on the pegs... and master yoda riding position... should be able to ride and ride and ride with no wrist or hand discomfort...
k75 with c bars...k75 with s bars...
both of my motobricks are as low as they will go... banjos 1/4" from fuel tank...
brick of the corn bars as low as they will go...
