I am 6ft 4in and about 260 lbs and this machine runs like it was made for me. I have only experienced one issue. When reving the v-max over 6000rpm (v-boost territory) I get an oil pressure warning when under a load. Does anyone else experience this? Yamaha is clueless about it according to my dealer who swears the oil in it is to spec. They suggested switching to a higher viscosity oil.?.
