| Harv,
A couple of quick questions:
Are you running a 14 tooth front sprocket? - I've heard that these are harder on the chain.
Did you recover the chain and work out where/why it failed?
Little story - I met up with some guys in France for a track day, they'd gone down 2 up on a Fireplace. The chain had snapped, atomised the chain guard and cut a big slice out of the side of whole seat unit. The pillion was unhurt, but he sure was a funny colour.
