After removing the FD, swing arm and transmission to do a front transmission leaking seal, new pivot bearings and the slave cylinder weep hole I now have a very loud clunk as soon as I start moving in 1st gear. Only happens the on the first cold move. Not warm. The swing arm and pivot bearings are NOT loose. It is something I took apart to do the above. I tiny little noise comes from the rear universal joint, but only by putting my ear up to the swing arm rotating in second gear. No unusual vibrations even at 60-80 mph. Oil did not get to the clutch. Suggestions please.
