Did you miss a shift? How high of an rpm do you think you were at? It sounds like Mr piston and Mr valve became better aquainted. I had that happen several times in my 400hp 302. Since it was a pushrod engine the pushrod was the weakest(and cheapest) link. Although I did bend several valves as well. With Rotax's OHC design things must be different. The cams lobe profile also dictates how well things remain in contact at high rpm. That is probably why the smaller cam is fine. Im guessing you have the lighter reciprocating parts like titanium retainers and checked the spring seat pressure.
