No, not required. The trans side cover will come off wether there is fluid in there or not. It will be messy if the fluid is not drained before removing the cover.So got the inner primary together (FINALY) got the clutch diaphragm spring to .003 the set screw 3/4 turn backed out from seated. Went to adjust the clutch cable and got it to spec of 1/8 free play. Gave er a light pull and it’s a brick. I’m preeeetty positive one or more of the balls in the ramp came out as I must have pushed the clutch lever in while everything was apart and I was taking down time to install the front pm brakes / swap handle bar controls.
Do I have to drain the trans in order to pop the side cover off and reset the ball/ ramp??
edit: she’s getting drained anyway. Fresh fluids all around.
