Roller cam chain conversion

[Camel]

I can't remember who I was talking too about this, but they told me someone had done the research on various aftermarket roller chain conversions for the busa. They mentioned a particular popular brand that turned out to be weaker than the OEM Hayabusa cam chain and another that was the much stronger than the OEM stuff.

I think the stronger roller chain was made by APE. Maybe.

Anyone know where the research is or know about it?
