I was probably revving the engine too high with out a load on it.
Too bad to hear this. As an extra precaution I've changed the conrod after the break-in finished (7 litres - about 1.5gallons). Conrod gets very pounded during break-in. Being old-schooled about this got me good results, and a conrod is cheaper than a brand new engine. Sorry to hear this.
P.S: The engine feels 'soft' but laptimes go easy at least for me. Would like a little more of mid-rpms (more wake...) Need to try to mess with it.
