Re: Bad O² sensor?
I swapped the O2 sensor for a universal one since the specific model was not available. To do so, I disconnected the battery. Swapping the part itself is not difficult, tedious is getting to it. While the panels were off, I did lubricate the gear linkage too... a huge difference there.
However, when I took the bike for a spin, she was popping and banging, no acceleration and the very fact of the engine running seemed to be hard work! Upon returning to the garage, I turned her off and mulled! Upon restarting, she seemed better. The idle is firm at 1,000 rpm, although on the motorway, the trip meter says I'm using more fuel but I haven't got the same amount of soot on the exhaust tip and the autonomy seems to be the same, not yet sure if better. I conclude less fuel being burnt. Although, I now have an intermittant flat spot between 1,500 and 2,500 rpm which causes a slight hesitance then surge back to normal acceleration.
Anyone have any suggestions why this strange behaviour?
Thanks in advance.
