Troubleshooting
Axle blocks feel loose in the swingarm
Verify that you have the correct model year for your bike, as swingarm dimensions can vary slightly across generations.
Alignment marks are difficult to see
Clean the blocks with a light solvent to remove chain lube build-up that may be obscuring the laser-etched lines.
