Is there only suppose to be a copper gasket? Mine looks like its been smashed from being put in wrong


The Copper ring is of the crush type, you get the exhaust gas seal from the deformity. Use a torque wrench (every nut and bolt on your bike has a spec. torque value) every time you re tighten (every off season) and the ring will flatten a little more each time, until it is flat as it will go. Then it's time for a new set. They last for years, if you use a torque wrench. There are a few tools and items a person absolutely needs to do their own wrenching on our bikes, 1/4, 3/8ths, 1/2" drive set of torque wrenches, a set of male and female metric thread chasers, a can of quality non-metallic base (bearing safe) anti-seize, Blue Loc-Tite, and a shop manual. Then you have given yourself every chance to not post on here about stripped out Aluminum threads/Heli-Coil repair kits and a host of other self inflicted mechanical malady s. Your fasteners will all be at their correct tension/stretch and your bike will be ultimately safer to ride.
