I suppose we should be relieved that it's the sprocket going. when I was in the Iom in 1999 after the TT lap every roller in the center chain section was in the bottom of the chain case ( but I seem to recall that about then we had the butt welded roller triplex chain issue) that was with a modified Miller it's not a new phenomenon back in the days of the MCC trials in the sixties I lost the teeth of a steel sprocket I should have remembered that years later in the Iom! high speed and the dynamo don't mix
