The beauty of an O2 sensor is it can handle this small change and adjust the fuel trim it self. So no tuning required, it actually has a suddenness in its acceleration, like I definitely have to hold on, it was surprising like I woke up it’s Super Moto heart. I considered making a tool to cut out the DB killer in the stock muffler but haven’t gotten started yet cause I had an epiphany. I will start crafting a tool and post a video on that as well. There’s a good chance I could make extras for anyone else who would be interested.
