Hi my dad and me are building a mini bike together.I entered it in the build off. But I want to be a bigger part than washing wheels and watching. I know more about go-karts so I'm clueless on mini bikes. So help me out.
Welcome to the forum! Tell your dad I said "Hi!"
In essence, a minibike is a go kart that's short a couple of wheels. The package may have a different presentation, but the fundamentals are pretty much the same.
The first thing you can do is drive your dad nuts asking questions and offering to do things. If you don't know how, ask him to show you, and instruct you. We learn by observing, asking questions, and trying things. Frankly, we learn by making mistakes, too- so don't be afraid to try something for fear of goofing up, and don't be too hard on yourself when you do goof up. I'm sure your dad won't steer you wrong!
