Hey all. Working on my first build and using a 79cc Predator. Not sure about gearing. Was thinking about using a direct drive 10/62 combo but also thinking about jackshaft with a 10/22/9/? setup. Just don't know what sprocket to use on the wheel to get me to around 40-45 mph. This will be a engine powered only bike. If this needs to be posted elsewhere, let me know and I'll move it. Thanks.
