Has anyone ever run one in the exhaust to help fine tune the carburation? I was planning on buying some of those weld in bungs for oxygen sensors and put them in the exhaust since I have the pipes off right now to sandblast and paint black. I have been thinking of the idea since I seen that you can buy air/fuel ratio gauges that hook up to an oxygen sensor. If it works for tuning automobile carbs, it should work for cycles, right?
