Sorry if this has been posted before. Just found it in my surfing:

Anyone got any feedback to give on how this compares to a Honda or Sudco tool? Ease of use? Quality?

Re: Tappet adjuster tool
Hi Nick,
you can find a bit to that point in the thread: " Periodic maintenance - cam chain adjustmet & valve adjustment"
However the nut position is not that crazy at the CB650 to urgently require a special tool. A strongly cranked 10mm ring spanner box end wrench perfectly does the job. Its more universal and probably cheaper than a special tool.

Hi Ibsen,
here is the 10mm ending of my 10/11 cranked ring spanner, the step height is about 23mm:
For work on Japanese motorcycles, a 10-12 like that may be more suitable:

Re: Tappet adjuster tool
I like it. It is probably also even better to handle than a ring spanner as there is some guiding along the screw/screwdriver axis also at the accessible level. Thinking about that, the ring spanner requires some nonzero feeling in your wrist. Very nice and creative!
Re: Tappet adjuster tool
Recently I made a special wrench for these plastic bottom bracket bearings of bicycles out of a garden hoe. It was a bit hardened (so I could leave a gap for the cam and do not have to remove the foot pedal first) and flat enough to fit beneath the foot pedal, so perfect from the practical point of view. Even the two forks on the other side can be used to plug on a tube for getting more torque.
But you can guess there is some room for style improvement. I can take a picture.

Re: Tappet adjuster tool
I do not have many self-made parts on my CB as usually the effort makes no sense (like I made the left mirror glass from some small rectangular mirror just to check if I can manage ) when I have or can get spare.
The situation is different for my XR as there the quality is significantly lower and I do not agree with several solutions there. After parts like the chain guide or the sprocked holder and some other fell apart, were fastly worn or broke to pieces, I made more robust versions myself. But it is also because I do not care for the optics of that dirtbike at all.
And of course making parts is always a good excuse to avoid other really boring work.

Honda tappet adjuster tool et al
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.......

Re: Tappet adjuster tool
This special tool provides some typical rural design marks
It is for bicycle bottom bracket bearings.

I was thinking about designing something myself... Something similar to Ibsen's design, but put a ratchet wrench on there instead of a stationary wrench.
I've never liked trying to hold the screwdriver still and removing/replacing the 10mm bolt adjustor to tighten the locknut. Maybe the ratchet would fix it?

Picked my adjustor tool up the other day. $25-ish Canadian. Can't wait to use it.
