So I recently bought a 03 gsxr 1000.. has a 16 tooth 530 front sprocket on it. The sprocket it had did not have a lip on it but had a washer. Is that washer sufficient enough to be able to torque it down with. It’s came loose twice since I’ve had it so far. This last time I put the sprocket on then washer and from what I understand it’s washer first then sprocket then nut. Just don’t understand why came loose..
