Not sure there was a different test other than the compression test that the dealer did on his bike, but they should know if you ask them to test to see if the rings seated/ or you think you're getting piston 'blow-by'......When he took the pistons out you could definitely see where all the blow-by was occurring. He was using oil, no sign of where it was going....exhaust pipes looked fine, not much coming out the breather, no leaks. But, one plug was fouling enough over a 500 to 1,000 mile period that it would start missing.....slight at first, then progressively get worse. I think it is a result of breaking 'em in to easy.....need to use Joe Minton's method of putting it under a 'load' a few times right at first so the rings don't 'glaze over'....once they do that, they'll apparently never seat in. good luck.
