I have installed a pair of Weber IDF 40 carbs on my GL1000 Street fighter. I could not get the jetting right until I hooked up an O2 sensor. I had the muffler shop weld a fitting in the pipe. The sensor came from the nearby tune up shop and the gauge is a $9.99 digital volt meter. Voltage runs from .1 volt, lean: to .9 volt. rich. The 14.7 ratio comes at .5 volt. Total cost, less than $50. In anyone would like more info get back. Bill San Diego
