EXHAUST SPIGOT 650 TRI UK - Replaces 70-3583
Exhaust spigot for the 650 twin cylinder head, current replacement for the earlier 70-3583.
This is the exhaust spigot for the 650 twin cylinder head, part number 70-9516, which took over from the older 70-3583. It's the fitting that the header pipe seats into and clamps against where the pipe meets the head, on the cylinder block and head assembly.

This number turns up in the parts books for the TR6R and T120R figures as well as the general cylinder block and head listings, so if your book still lists 70-3583 for this position, 70-9516 is the current number for the same part.
If you're chasing an exhaust leak at the head or replacing a stripped or cracked spigot, this is the part to check. Confirm against your own head casting before ordering since spigots wear and get swapped over the years.
