I have a couple problems with my gearbox.
First off, my oil is black and my rear wheel is wobbly. I put a new bearing in the rear wheel over the winter and my wheel hasn't been right since. I am having a hard time finding what part number to order for a new stock bearing. My replacement was a SKF from scootercraft that looked correct, but I guess it wasn't.
Secondly, is there a gearbox gasket? I've been putting it together with gearbox RTV.
