So i finally got round to doing mine, upon inspection it did not need doing but as i had amassed all the parts and tools i thought why not.
very straight forward job, the only things that puzzled me were , "why drain the coolant" and "why drain the oil" , the coolant pump came of as a unit and didn't need draining and with the bike tilted on the sidestand i only lost 1ltr oil from the side casing....Alas i changed the oil in the end as i bought fresh stuff and new filter.. I nearly broke the balance drive shaft , whooot,, I read here that any nut with a slit in the edges is a reverse thread,, not the case for the nut on mine ,,(balance shaft gear nut),i used my electric windy gun to free it off and ended up tightening the thing up so hard it almost rounded off the nut ,,shit my pants,,
so i took some photos and made a slide show for you all,,
