I've always wanted to grab one and refit a more capable fuel system.

Since I got to know about the TS3 I wanted to get one and fit into some Chevy full-size truck.

I feel two strokes are dismissed as being too noisy and dirty without digging deeper into the design.

When it comes to 2-strokes, nowadays most people seem to forget the Diesel ones and only remind spark-ignited applications. Well, at least most 2-stroke Diesels resorted to an oil recirculation lube system, which makes it easier to implement some emission controls which became mainstream such as EGR.

An extended stroke TS3 can allow us to provide a head with an intake valve system reducing that source of oil bypass.

The absence of a cylinder head is actually a desirable feature, since there is a smaller surface for heat losses through irradiation, thus the engine can convert more energy into motion instead of just waste it.
