Does anybody know of anyone who offers a service machining out and rethreading  flogged out threads on the exhaust port on early Bultaco stuff. J

I have some 8mm steel threaded rings made up that can be screw attached to the outside edge of a barrell (or recessed in with machining). The exhaust pipe ring can then be screwed into this. Let me know if you want.
