Hello Peter, and (Bazlerker) The reason it went is a mystery as it was recently completely done by an expert, lasted about two starts only but failed when trying to kick, I have had a D Shadow with the same ES for years and never had a problem, on this bike it has happened twice in one month? Both times trying to kick start it, Made a clanking and everything locked up, this meant that as last time again the chain had to be disconnected from the rear wheel in order to move the bike! Good job the link was in a visible place.
I was not aware Grosset would sell the parts to anyone so I will google him and hope he can help. If anyone has any ideas please advise, Incidentally, the 'circlip' had come off so everyone will say that was the reason for failure but I don't think so, the circlip was undamaged but off, the expert did not fit a new one as it was not available but both large cog and this as shown in my photo shown were replaced, I would hope for a better type of circlip and still like the Yamaha part number?
Thanks, Kerry.
