In answer to your questions, tyres are oe siracs only done 2000 miles , at the time I was accelerating but not to hard . Pleiades , i'm going to put the original dog bones back on and raise the forks to try(not sure I' ll be able to get my leg over , old bones not so supple any more) don't think the shock is to soft as have no wallowing problems , may play with the rebound damping and fork adjustment ? Any ideas gratefully recieved .
