This is the racing version of the concept, it sounds very much like there is almost no flywheel mass.

Zenoah makes a cool 66cc opposed twin similar to that Wooler engine, mounted up to a 90 degree transmission it would make a neat mini BMW, albiet for way too much money! lol

I think that twin will be a very fun and economical way to fit a twin to a small motorcycle A.G., great work!

Interesting. Do you have a pic or link for the Zenoah? I have never found anything remotely like the Wooler.

There are a few companies making flat twin 2 strokes, even flat 4s. Depending how big you want to go, you can even use microlight/drone engines:

wow!
I want a flat twin, surely someone could make a set of cases and a crank for two HT barrels. Even a couple of 49cc pocket bike jugs?

This is a opposed twin build that I just started. I was going to jack shaft it to the crank and use the three speed drive but have thought better of that. This engine should have enough power for the speed that a lightweight tire can handel. Instead I'll just run a belt drive and save the 3 speed for peddling.

I am also working on a vee twin engine like so many others are.

KOOOOOL what is the engine off of...........Curt
It is an old tecumseh twin. they made them for a few different bicycles but also used them on a lawnmower for a short time. 50's 60's.
Picked it up cheap on e-bay. I'll start a thread when I get further along. Got tired of seeing the engine sitting around.
