Riding along nice as pie and the crank just snapped in half. Luckily I was only doing about 30mph so I just pulled the clutch in and coasted to a halt. Un-luckily, the break had utterly destroyed the con rods, crank and also the cases. The barrels and pistons etc do seem to be ok, but it's just sole destroying after all the time and effort I have put into getting that bike right over the past few years.
