Versy's Valve Adjustment Tool
10/21/16 at 22:39:28

This is the doohickie that I use to adjust my valves.

Take a fender washer with a 1/4" hole in and press a screwdriver bit in it.
I scribed 2 sets of lines 90° apart then put notches in the sides cause when it's dark you can't see the lines. 90° turns out to be about .006" so make a few adjustments with it and scribe off your favorite gap.

To use:
loosen the locknut with a wrench, you can leave it in place.
put the screwdriver bit in the slot and run the adjustment screw down to the valve.
eyeball a scribe line with a convenient feature then turn the tool to your favorite adjustment point.

It came in a kit with a ratchet driver that I got a long time ago. I've been thinking of replacing the fender washer with a purpose built disk that is larger. Big enough so it clears the frame so turning it is easier.

I will choose a bit that fits snugly and go from there. The bit that you are using now looks like it came from a Chapman's set. Kenny G

I'm a bit confused. While I understand the concept, I don't understand the 90 and 6 thing. Are you saying 90 degree of turn is about .006" in gap?

Main main aggravation with valves is that the adjustment screw moves when you tighten the nut. I need to make one of them other dohickey things (tappet wrench).. or find one that actually fits and works on the LS650.. in the frame.

Most motorcycle problems are caused by the nut between the seat and the handlebars. Make sure yours isn't too tight or too loose.

Philips on one end, flat on the other. Used a grinder to shape the Philips ends into flat blades , aimed different directions. I can hold the adjustment as I tighten the jam nut. If the adjuster threads aren't close fitting that will open the adjustment up a hair.

You're right... my bad... fixed, should be 90° is about .006"

With this doohickie, you can hold the adjustment screw in position while you lock the nut down.
and I just use a standard craftsman combo wrench.

Youzguyz-
To translate Verslagen's very clever method:
Thread pitch of the valve adjuster is .75mm
Meaning one full turn is .75mm
1/4 turn would be .1875mm
.1875 divided by 25.4 equals .00738"

The #2 and 3 exhaust valves on single cam CB750 Hondas are a real PITA to get to. We used to use this kind of technique on those bikes.
