I have an 06 R that I proudly put 14k (first street bike) on in two summers. I checked the valves last winter and am ready to do it again here soon. My question is, when I was checking the rear exhaust valve (pardon if these are the wrong terms) it seemed like the rod above the valve would lift when I inserted the guage. This makes it seem like you wouldn't get an accurate reading with the lifting. Is this normal? What am I doing wrong? Thanks.
