Just to slightly sidetrack things, have you seen this Ed?

Yeah, they had one of these on display at my local Honda Powerhouse bike
shop, and the owner spent some time showing it to me. Very interesting.


You've seen it in person? I'm envious........

Here's a good article on fuels and detonation (gasoline based).

Thank you Pete. This guy agrees with my explanation of detonation
being caused by the dissassociation of hydrocarbons and production of
free radicals in the cyl.

Ed, what say you?
Is this guy out in left field, or do you agree ?

The research I saw says that the different intermediate products of
different fuels produce very different burn characteristics. So the "free
radicals" explanation is a simplification that works for what he's
discussing in this article. It doesn't help much when you're comparing a
variety of fuels, such as the ones in your list.

I see from the abstracts that there is SAE-published research on this very
subject, but I'm not about to spend money for it.
