Well now that its summer im back and finally have time to play with my bike i did a simple tear down and cleaned it up when i noticed something. My rear sprocket does not line up with my pinion gear. hmm maybe that explains why my chain keeps falling off? I have the bell housing with the 3rd bearing support so would it be possible to unscrew the pinion gear out a little to get it to line up with my sprocket? im sure i wont be able to use the 3rd bearing support anymore but i dont have it on anyways, or is that thing important?
