Just finished checking the valve lash on my bike (see signature).
The new cam chain tension tool, Honda P/N 07AMG-001A100
worked great on the left side. Had a problem on the right side, as the frame prevented me from being able to insert the tool into the cam chain tensioner release.
I made the following adjustment:
The bronze-colored knurled knob is held on the shaft by a set screw. I used a very small (about 2mm) allen wrench to loosen the set screw and move the knurled knob down the shaft a bit, as shown in the pic (before the adjustment, the knurled knob was flush with the end of the shaft). The tool worked great on both sides after that.
