Bought a new left-over 01 XR650R for $3999. Very excited! Bought Baja Designs dual sport kit, uncorking kit and Uni filter. 15 years ago, I had an 87 XR600 so kinda familiar with uncorking. Question: the needle jet (not the needle itself, but the jet with one tapered end that goes in under the main jet and needle jet holder) does not fit. It is too big for the diameter of the appeture it is going into and will not go in far enough to allow threading of the needle jet holder. Did Baja Designs send me the wrong needle jet? Do I have to increase size of appeture? I half remember seeing something about using a drill to increase size of the hole. Thanks for your help!
