7 posts in this topic

How common are they? I ve heard a local pro has had his fail twice already. Considering a new bike and want to check to see if this is common or not.

Thought the new design (offset crank I believe?) was supposed to be better on the rod? Weird. Hope mine holds up.

The bore offset reduces thrust on the piston and bore walls during the power stroke, but doesn't have much effect on the rod itself. Since there are no specifics (so far, this hasn't risen much above rumor or urban legend), there's not even enough information to speculate with.
