Excessive revving of duacti engines can result in oily unpleasantness!
75bhp at 11,000 rpm is very nice, but you'd better have a blueprinted engine including balanced pistons. There's always a good chance of bent valves, blown head gaskets, etc, when running an engine at its very limits, and rebuilds rarely come in at less than four figures. Is this series really at a stage where this is normal for the series leaders? Madness.
