hi all, just wondering if o2 sencors should be cleaned or replaced after x amount of time, cheers BRUSH.

thanks hilly, but when do you know there faulty, bike has just picked up a bit of a miss now and then around 100ks, gunna change plugs and see how it goes or could be bad fuel, thought its a 2007 maybe the sencors are fouled dunno much about them,  cheers brush 

yep...plus I'm pretty sure tat a buggered O2 sensor will not cause a miss.
