DIY 16 valve adjustment tool,...

[Guest]

Here's a very inexpensive tool to help rotate the small square valve clearance adjustment screws on a GS1100E I'm resurecting.

It's a #2 Robertson head screw, this one is a 2.5" long version and I've modified it by grinding the outer edge of the head down a bit on a belt sander.
That just makes the business end of the tool smaller with more clearance for the wrench.

Being in Canada this is the most common sized screw head configuration there is and I'm probally no further than 10 feet away from one at any time.
Your availability may be different in other countries,...ie., in the USA its much more common to see Phillips head screws.

It fits on the Suzuki adjustment screw perfectly tight.
I like this lengh as it gives me plenty to grip on.


Full credit to a picture I found online showing a #2 Robertson screw mounted in a plastic wire nut.

I tried that and found it a little small to hang onto.

Welcome to the site.

I guess it is a better use of construction items that the typical Saws-All

For deck screws the Robertson heads work very well, but I have a box of stainless screws that horribly strip worse than any philips head.

It works even better if you screw it into the end of a 1/2" dowel, which makes a great handle.

After using a Robertson once, I decided that my time & frustration is more expensive than the MotionPro tool.

There's no reason you can't get the job done with the various Robertson 'tools', but that nice big comfortable knurled knob on the 'correct' tool just gives me more control over the clearance, and it holds a lot better when you snug the locknut down.

It's still necessary to anticipate how much the locknut is going to change the clearance, etc., but in my experience, the MotionPro requires far less patience to get the results I'm after. Maybe I'm just becoming a tool snob; I can live with that.

Great idea.

Well if you could put on something the size of a spool and knurl the outside, that would be pretty nice

It's done as far as I will take it or need it.

As long as it does what you need... that's what counts.

Motion pro carries a nice interchangeable set of three different types of adjusters for the screw adjustment valves. I finally bought the set and wondered how I ever adjusted my valves with out them. They make it soooooo much easier now. I use a socket to brake loose the jam nut and adjust from there. I'll use the socket for the final tighten. Just make sure you do a final check after that. I also ordered the angled feeler gauges, they work really nice too.

I adjusted the valves today with the DIY tool.

Certainly better than trying to hold onto the small square adjusted end with a crescent wrench and tighening the jam nut.
The specific designed/produced tools, especially the ones that have the screw adjuster passing thru the wrench would be better.

Ok, getting closer to seeing if this thing will run after 6+ years hidden away in a carport.

Now,...how to get those freshened up carbs and airbox back into place?.

I had an old ignition wrench that fit.
