Secondary air injection "EGR" plug
So I removed the air injection on the side of the engine head, because it was causing back firing with my new "catless" exhaust.
Instead of making a block-off plate, I took the risky move and tapped a thread for a M12 x 1.5 bolt. There a lot of metal shavings making the thread, I used a shopvac about every turn of the thread. The aluminum head is very soft expect shavings even when tightening a bolt. I got several bolts to try. If the anodized red is too much I can always spray some high temp black primer on it. Let me know what you guys think!
