You aren't the only one looking at the top end of your Triumph wondering what to do with the the stripped out exhaust pipe adapter. It happens more often than we'd like to think which is why we offer the product.
This exhaust adapter spigot is oversized .010 from the originals with a slightly coarser thread to cut new threads in the head.
Note: If the head is still on the bike make sure the valves are closed so you don't end up with shavings in your motor. Also apply this product with loc-tite. It's one and done so make sure you thread it in straight!
