Bolt Exhaust pipe to cylinder head
The bolt that clamps the exhaust pipe to the cylinder head on the exhaust clip assembly.
70-6744 is the bolt that holds the exhaust pipe clamp to the cylinder head, part of the fitting that clamps the header pipe up against the port. It shows up across a run of exhaust pipe and muffler figures, including the folding footrest variant on the TR6C, so it's a piece that stayed in the parts books through several years of the exhaust setup.

On the bike it works with the exhaust clamp itself to keep the pipe seated tight against the head, which matters for keeping the joint from leaking or rattling loose over time. The old book number for this one was E6744, so if you're working from an older catalog and see that number, it's the same bolt.
These are small parts that walk off or snap from corrosion more often than people expect, so it's worth checking the threads and the clamp fit before you put the pipe back on.
