It is my understanding that we should use 75W-140 in the gearbox, and 75W-90 in the rear bevel gears, is this correct. Some older threads seemed confusing.
All that is easy to obtain is Royal Purple MaxGear synthetic oil. But it contains a friction modifier, and it states not to be used in wet clutches. Isn't the RT clutch in the gearbox? I have had too many bikes and am getting them confused in my old age .... Ha.
