When I got mine done I undid the access bolts between the headers and the cats and put the probe in the hole. It appears that there is such a variation in everyone’s final settings that a proper reading needs to be done. The readings between the left and right don’t necessarily match up either...<!--QuoteEnd--><!--QuoteEEnd-->


my TDM and my mates TDM are 2003 models and it can be seen in the workshop manual two take off points on the exhaust down pipes for the CO readings to be measured from but neither of our bikes have them? so where is it measured from.
Any body out ther know of a yamaha tech that can explain!!!!!!!!!!
