Right! I've formulated a battle plan. ...I've just got back from my friends classic kawasaki parts store, new and second hand, I bought the whole final drive cover just in case, the clutch pushrod and bearing, the screw and nut part which is probably broken on mine, while I was there I got an underseat tool kit (finally!) Exhaust collars which although second hand are much better than mine and finally nos covers for the speedo and tacho £50 all together
oh and I've just ordered one of those dark green service manuals from eBay, that cost £48 by itself! !
