If you are working on a vintage Norton Commando cylinder head or a Triumph head, often times you might find that the exhaust spigot threads may be stripped. If so, they will need to be repaired..

In this listing you will find exhaust spigot repair inserts for sale; we have a few different variations. Our inserts will require a skilled machinist to bore the existing exhaust threads followed by pressing in our new insert

With the proper press-fit (.002″-.003″), there will be no need for welding as the insert will be locked in place. All inserts are made in the USA from 6061 aluminum
