Firstly, thanks to all that took the trouble to reply regarding the RS.\n\nStory thus far; had generator off left of crank and centrifugal filter and\ncrank drive gear off r/h/s. Can't feel any play at all in the mains\n(they're brand new, as is big-end).\n\nEverything that's supposed to be there is, and everything is tightened up\nproperly.\n\nLoads of compression, all gears there, clutch works etc. Tried to feel any\nplay between generator and crank before removing, but can't feel anything.\n\nHaven't removed the top-end (yet) for simple reason of if I need to get\nsomeone to listen to it - to give a diagnosis - it obviously needs to be\nrunning. Still sounds like big-end...anyone here ever had a new big-end\nfitted and still had similar noise after??\n\nThanks,\n\nRick.
