John,

The twin you suggest is, most likely, wider at the head, than a single cylinder engine. The engine will also be inverted. So now I have two cylinders to deal with and not one. Two plugs that can fowl and not one. Not to mention twice as many moving parts.

With all this said, I'm electing to deal with ony one cylinder. I'm currently thinking the YS 170 4S.

But it's a fine looking twin.

Thanks for the reply.

Charles
