View Full Version : AFR Sensor Positioning

It appears I might need to have a bung moved/added to a Ti system after the collector pipe. Any recommendations for shops?
Reason being, the exhaust is on a v-twin and has a bung after each cylinder, but the AFR module appears to only have the ability to monitor one sensor. Would it be ill-advised to position the sensor after a single cylinder and just run with that?

Problems with your bunghole, Kyle?

lol....
The EVO 4 exhaust on the KTM doesn't have a bung on the collector pipe :(...
I thought about it some more and kept googling. I think the pulses and lapses in flow will give me an incorrect AFR reading.
Need a Ti weld shop.
Maybe not?
Well in the interim, it looks like it SHOULD be ok on just one cylinder. I imagine a modern motorcycle is synced fairly well. That and there are only two cylinders, limiting the chances they are that out of sync.

Check with Bart, Smitty might be able to weld ti. General Air off I-25 used to stock ti sticks.
