O2 sensor woes....

How did you find it ran without the lambda compared to with it?

Fractionally smoother without the sensor if that makes sense.... remembering from the olden days setting up the carbs on my ancient range rover, you could just feel and hear the engine perk up going from lean to rich.

Still pulls well but just a little thrashy under load, definitely needs fattening up throughout the mid range I think.

It's nice to know that you found it a bit better without the lambda sensor & no signs of going into limp mode as suggested.

Just because it no longer runs lean, doesn't automatically mean it runs rich.
It's not called failsafe for nothing.

I must try it with the 650 as a looksee.
I did once disconnect the lambda, ait, map & pair on another bike for a trial & the bike ran absolutely lovely - almost like a nicely setup carb'd bike ;)
