Re: High Performance Pistons...anyone?
In the last several months in Roadracing World, Sam Fleming from Army of Darkness Endurance racing team has a series discussing how to prep a bike from stock to a high performance, reliable endurance racer.
He says that unless the bore is changed, the current 'slipper' type pistons which are treated with ceramic type coatings are as good as any aftermarket pistons.
(Of course, if you're increasing compression by turbocharging, N0s, etc, I'd think about it.)
You should check out that series of articles, it's got a title like "All is Vanity", the destruction of carefully engineered parts, or something...
He's a good writer, and his section on how the engine is torqued together is really interesting. He says that alone can affect a 600 engine by 5 horsepower.
