O.K. As I said I'm new. I purchased the bike from from a friend and he did a really great job at building it considering the fact that I have not done any real maintenance and it still runs after 2 months. It is beginning to run rough and I have no idea of how to maintain this great bike. He gave me a few tips but to be honest I would like to know how to fix my bicycle on my own. He seems to think that I need to clean or replace my carburetor. The problem is I don't know what the heck I'm doing and I would really like to know if there is a video on how to build a motorized bike from the wheels up. That way I can take care of all my issues myself. I feel that if I can start taking care of the bike properly that it will last me a long time. I'm pretty good at following instructions and grasping "why" things need to be done in a certain way. If I could just find detailed videos. For example, how do you adjust a carburetor so that it runs more smoothly, how do you take a link out of the chain so that it isn't loose, how do you tighten your brakes and so on and so on and so on. I would like to know all I can about how this wonderful piece of machinery works.
