Have you read this?
These guys and clever dog have some great tricks to make these bikes perform alot better

We have a full race 175 sloper and 240cc sloper both in 160 frames. They are a neat little bike. 5 speed trans from a 175 can be fitted but requires some welding and machining. 175 pistons don't fit inside a 160 head, so that's not a viable option. I built a 204cc motor for a guy a couple of years ago and that could be repeated. It went from 50mm bore to 56mm with stock 160 carbs and was a fast race bike. With a street cam it would make a nice street motor even with stock 4 speed. We fitted larger valves and spring kit etc, but a lot of things are possible on those motors. That frame will need to be braced now it's all bendy and flexible. Flexible is great in a human, but not so good in a motorcycle.
If you don't plan on using that front fender, I'd like to trade you something for it. I need a stock front fender.
We're just across the border if you need some inspiration.

175 sloper was a one year anomaly . 5 speed bottom end in what are basically 160 cases. head is unique too. Deeper chambers like all 175s but with low level ports. 160 and sloper motors do not flow as well as as vertical heads but they flow more than the engine can use if you pay attention to the exhaust ports.
If you are tempted to buy a cam - get the mildest Megacycle cam. Our tests on track and dyno suggest it's best for a mild motor.
You can modify a 160 to take a later model 5 speed trans.

Looks like you got some great inspiration! You get any ink while you were there?
