A Suzuki OEM gasket for the Cam Chain Tensioner. You are going to need it if you work on your starter motor. It is not a good idea to re-use this gasket. If it blows out, it will dump a large amount of oil onto your right foot.

Your automatic cam chain tensioner is spring loaded. This can make it difficult to install as it wants to extend before you have it bolted into place. This handy tool will back off the cam chain tensioner mechanism and hold it for you. No more awkward 3-handed contortions are required to get the tensioner installed.
