Doing a chain/sprocket change today on my gsxr and made a simple device for locking the front sprocket. Cut off about 80 links of the old chain. Fold 3 links of the chain back on itself until it forms a 40mm eye on one end. Butt weld both sides of the 3 links. Cut a piece of steel tubing about the same diametre as the rear axle and about 100mm longer. Slide the tubing through the swingarm and the eye in the chain. Run the loose end of the chain over the top of the front sprocket and undo the retainer nut. Run the loose end of the chain around the bottom of the new sprocket and retorque the nut. Simple. Have a blast, Paul.
