Hello,

Yesterday on a trip the warning light started flashing 2 long 4 short, meaning a problem with the O2 sensor.

As far as I know, the bike has no modifications here...I notice the bike is shaking more now, and consuming a lot more fuel...

What should I check first, any ideias? And if I need to replace the o2 sensor, how to do it? I hear it�s quite expensive? :/

Also, I see in ebay some 02 sensor elimination plug, whats that about? I have zero knowledge on FI..... :/

Thanks for your help!!
