Could someone please explain to me how to ACCURATELY measure mid valve float, or any valve float(ACCURATELY) for that matter?? I did a little tinkering on the mid this weekend, and it made a huge difference for the better. but just visually, and trying to physically move the mid on the post to check it for function I could tell that one stack didn't 'float' as much as the other stack. could there be the possibility that both posts aren't the same dimensions? for the record, I decreased the float .15 MM, and installed a 10x17 in the mid stack. One side still had visible float, and other side was visibly tighter. 2006 kx450f, with gold valves. I also lightened base 2 'steps' on my chart. thanks for the replies and knowledge.
