Hello and I would like to comment that - as an owner of a 1984 standard R65 I am replacing the bearings for the second time in 15 years. I'm on my second restoration of the bike and I felt that once I had removed the swingarm I had - in effect - disturbed the bearings and surfaces. They will wear out - as I could see from the bearing surfaces that were removed on both occasions - 1996 and also this year. They are a very cheap part to replace and a local competent bike shop should be able to refit the new bearings for you. So, just check the bearing surface to see if it has been marked - looks like a dark shadow all round. I have never had any swingarm free play in all the time I have had the bike - since 1992 - but I like to be cautious - hell how mad would I be with myself if I didn't do this having restored the bike fully and a year later I have to pull the back end down again for a couple of cheap bearings.
Worth a thought maybe - Adrian ........................
