    Sprockets Sprocket spacer for tapered axle?

    So I bought a freewheel rear wheel for my Schwinn project. I also have a 38T sprocket with CNC hub adapter. However, I have noticed that it is a tapered hub, and it it is 0.68" at the center, and 1" at the ends. Any way to shim up the difference?

    Cutting rag joint in half...?

    Hey Everyone, This is my first post on the forum. I'm working on my first build and finally finished it up but realized my chain alignment was really bad and creating this "popping" noise. The only way I can see to bring the drive sprocket and rear sprocket into alignment is to thin the outer...

    Maintenance questions, and air leak?

    Hey guys, first post so excuse me if this is in the wrong section. I'd say this engine has around 1000 or so km on it, and since day one I've had fuel/oil dripping onto the engine, not sure if it is from the spark plug, exhaust or crank case but I have made sure all is tight. The bike goes great...

    Chain attatched to centre sprocket?

    Ok so on my bike, the chain is connected from the gear on the engine, to the sprocket on the rear wheel. Recently, I've seen pictures of motorized bikes with the chain attached from the engine sprocket to the centre sprocket. Would this gearing result in better performance? I'm aware it looks...

    I just noticed this but my chain tightener/tensioner isn't on right. The tube it's on isn't shaped right so it doesn't fit on correctly. We positioned it so it doesn't jam but every now and then there is a loud pop coming from the chain. I believe it's because the chain is coming off the...
