Mikuni VM26 Carb Slide Adjustment

I have been known to be a tad bit anal about measuring things in the past which is why I have multiple tools for accomplishing such tasks. How many 1" micrometers does a person really need? Well in my case three (3) to triple check important measurements. Anyway when I started the process of refurbishing my '77 KZ-1000 (I don't like to call it a restoration quite yet) I learned that I needed an accurate way of measuring the initial VM26 carb slide to bore gap which per the manual is .028". The manual states one can use a piece of wire for this, but I just couldn't come up with anything that was close to what I was looking for. After scouting around on the internet I discovered that a 22 gauge hypodermic needle is .028" in diameter. I located a 3.50" long spinal needle in 22 gauge which works great for this job. I also located a company on the east coast that makes .028" diameter tungsten carbide rods that are 6" long. These rods also works great for this job and I think cost me like $10.00 and came in a nice plastic storage tube.

Now I am sure many of you have your own self found measuring tools for accomplishing setting the slide to bore gap, but this is just two of the ways I have found of doing this. I am not sure how long the hypo needles will last, but the tungsten carbide rod will last a long time and you can even fabricate little handles on one end to help in their use. If you are interested in obtaining the rods just send me a PM and I will give you the ordering info. We now return you to your normal programming.

Some 0,028" = 0,700 mm drill bits did the same effect for a static cab sync after a rebuild for a good starting point. You have to do a vaccum sync later on a runnig engine anyway, so some slides will get off the 0,028" reference adjustment.

A piece of irrigation wire is all you need. They just have to be even.

I use copper picture wire from Home Depot. I think it's 22 gauge but can't recall. A roll will last a lifetime.
