1 3/4″ nuts 16TPI

Trying to find 1 – 3/4″ nuts with 16 threads per inch. This is to clamp down new exhaust stubs I want to make, replacing the ring exhaust. Had a first look around today here in town, but no luck so far. Will try a few more shops….

What ever I get, I am sure they need to be machined. So maybe I just need to have some made up in the end if I can’t find any.

Other option of course is to put the ring exhaust back on again, and see what the power output does!


You can see 5 of them here in this photo. They looks like a ring slid over the mixture and exhaust pipe, shrewd onto the cylinder…… Mine will probably look different. Will see.
