It's a 12mm for the cylinder and headWell you need an 8mm for the clutch cover, 17 for the stator, 19 for the clutch basket, 7/8(21mm) for the clutch gears, 13 for the cylinder and head, snap ring pliars, for some of the gears down there, a torch and a large metal piece for putting the cases back together, you're probably going to need kens videos if its your first time, and a flywheel puller.
with this from HF it could push the crank and separate the cases?
Roger that been watching video after video nothing seems too hard. Had someone tell me to take the cases apart with a chisel WTF.....
