I have an 04 400ex with a 38t rear sprocket. I need a bigger diameter sprocket due to chain rubbing. What are some good recommendations?
Well, the frame is a 400ex...... the engine..... is a BMW S1000RR 😅 because of the way the engine is mounted, the chain is rubbing on the swing arm. I need a bigger diameter sprocket to give it that tiny bit of clearance.What is the chain rubbing on? I would suspect an incorrect or worn out chain.
