Great build, thanks for the pics and info. Please keep up the good work. I have done the doohickey and the $.22 fix for the carb on my KLR's. I am not a particularly good wrench, but I would recommend that you take a look at the carb while you have everything off. Just generally checking of the float bowl and the diaphragm. And the $.22 fix (which cost me $.47, inflation) is really simple, though maybe unnecessary at higher altitudes.
Keep up the good work and thanks again. I am subscribed.
