I've had a good bit of experience with a similar engine, it was a suzuki 90. It had a rotary valve behind the carb, you can change intake port timing by trimming the fin of the disc/valve.

Uses a rotor vane instead of a piston or reeds. They are sweet. Check out the stuffing muffin guy on YouTube. He runs them. He uses one on his land speed record 50cc bike.

If you look at the first picture above you can see that the carb is mounted behind the side cover, the valve/disc is splined and rotates with the crankshaft.

I actually have one of those too. I bought it off eBay for $50 to play around with. I wanted to checkout a disk valve. I fixed it up mechanically. I don’t have the electrical components, but I never planned to put it in anything anyways.
