can you buy it over the counter at a Honda dealership and do you have a part number.
I ordered mine last week from Orange County Honda and they had it a few days later. The part number stamped on it is 07903-3230000.

I just went into our local Honda shop this pm to ask about the price hereabouts (BC, Canada). I was quoted $24cdn. The part number for the CB650 tool is 07908-3230000.
FWIW I adjusted the clearance on my 650 shortly after I got it in May, using the go-no-go method. I was very proud of myself when done, but it did not seem to make the top end any quieter. Anyhoo after the ride up north and back (2,000km round trip) I thought I would do a double check. It's not like this is a difficult job (and WAY easier than getting to the top end of my old VFR800) and I had an hour free.
Well, all I can say is that a '79 CB650 runs fine with the clearances adjusted to .005 and .008 thou. D'oh! I adjusted them using the thou measurement on the feelers, thinking I was measuring in mm. D'oh again! I had a good look at the cam lobes and it doesn't look like it suffered. I seldom rev over 6,000rpm, so maybe I was lucky.......
