Hey dudes and dudettes, how are ya?
My current EFI project requires an O2 sensor bung to be welded to an exhaust system... on a 50cc engine. You can imagine how small that exhaust pipe is. If you can't, it's about 23mm or 9/10 In. OD.
Question 1; With said tiny pipe, should I buy a stepped/tall/angled/normal bung?
Question 2; If I buy a weld-on bung and bring it and the exhaust pipe into a muffler shop and ask them to weld on the bung, are they going to tell me that the pipe is too small to weld onto and laugh their arses off after I leave?
