[QUOTE="oexing, post: 101331, member: 1493"] You are quite right, basically you´d need two sensors per two carbs, but it is not practical on the Vincent when you like to hide the permanent M 18x1.5 weld-in thread. Best place seems to be in the ex pipe just before it enters the silencer, in horizontal orientation - I guess. You will choose the heated four wire sensor type as on a single or twin there is not enough heat at that distance from the cylinder. I´d get new needle jets and needles anyway as these components can wear and when doing road tests you change any components in both carbs with same sizes of course. That should be close enough even when having only one sensor per two carbs like with the BMW setup. These exhaust sniffers, are they the CO or CO2 testers ? You would not find them at small costs with battery power and small sizes to be used for bike road tests ? The O2 sensor plus voltmeter is only around € 30.- so no big deal to have it on the bike for some time. I am still busy with a Bing carb configuration on one Horex 460 , no spares for that type of Bing so this will go on for a while tweaking carb components for smooth operation at all conditions.
