Troubleshoot Suzuki GSX-R1000 Starting Problems
When your Suzuki GSX-R1000 won't start, troubleshooting the problems can be done with a variety of simple tests.
This guide will walk you through some basic steps you can take to identify and resolve starting problems on your GSXR motorcycle. Before you begin, check out the many exploded GSX-R1000 parts diagrams (click on a component from the list to open its diagram) that show you where the parts are on your motorcycle, and how they fit together.

Suzuki GSX-R1000 Starting Problems:Troubleshooting Tips
Step 1. Remove the seat by taking out the two 4mm bolts and lifting it off the motorcycle.
Step 2. Check that the positive and negative battery cables are tightened and secure at the battery terminals.
Step 3. Make sure the battery is properly charged. The video below shows you how to test a Suzuki GSX-R1000 battery.
Step 4. Check the starter relay fuse, which is tucked up under the tail fairing just behind the battery. Remove the relay's plastic cover. Test the fuse by turning on the GSXR's ignition, putting one end of the test light on the negative terminal of the battery and the other end on each side of the relay fuse. If neither side of the fuse is getting voltage, that means the fuse has blown. There should be a spare fuse in the relay's plastic housing, and replacement fuses are available on Partzilla if your bike doesn't already have one.
Step 5. Check the starter relay assembly by first disconnecting the cable that runs from the relay assembly to the starter motor. This prevents the starter from engaging when you press the starter button, so you can hear if the relay is working. Put the test light on the yellow and green wire that runs to the relay assembly and press the starter button. The test light should illuminate and the relay assembly should make a clicking sound as its internal switch operates.
Next, put the test light on the relay terminal that runs to the starter motor and press the starter button. Once again, the test light should illuminate and the relay assembly should make a clicking sound. If the light doesn't illuminate and the relay is silent during these tests, the relay assembly has failed and needs to be replaced. However, if the tests are successful, it means the starter button and the relay assembly are working correctly, and the problem could be the starter motor. Before buying a new starter motor, we recommend taking the next step.
Step 6. Test the clutch switch, which prevents the motorcycle from starting when it's in gear, but can also prevent the bike from starting at all if it fails. Run your test light from a positive junction (battery, relay assembly, etc.), and put the other end of the test light on the upper of the two wires that connect to the clutch switch on the handlebars. Pull the clutch lever in and the test light should illuminate. If the light doesn't illuminate, the clutch switch is faulty and needs replacing.
