I recently started mods on a stock 1hp Free Spirit. I added a 50cc TCCD, 15mm bing clone, tecno circuit, and a 16t front sprocket.
It now has a tough time starting, idles rough, bogs sometimes at low speeds, and when it doesn't, it definitely bogs at high speeds (high 20s low 30s), and the acceleration is pretty shit.
The throttle cable is a bit loose where it meets the carb and at the handlebars. Besides that, any idea what I should be addressing?
