Hi - I am having problems removing the clutch cover on my RD350lc. It appears to be because of the water pipe which passes through the crankcase is stuck - both in the hole (there is a slight ridge in the pipe) and in the clutch cover (I presume it is a separate part). I have tried gentle taps with rubber hammer, and a carefully wedged screwdriver without success. Ideas please. Thanks in advance
