Sounds like a 2 stroke to me, especially with the revs to
keep it alive. Needs a bit of tuning. I'd have to see a
phote of a head to believe it's a 4 stroke.

Awhile back there was a discussion about a 4 cylinder 250. Here's a link
to video of a 6 cylinder 250cc Honda.

I remember reading an article about that engine.


(No rockers, cam drove the valve stems directly.)

You can't get any less valve train mass than that. It must of had a very
high rev limit before the valves started to float.
