Idle Mixture Adjuster

Do you tune your engine for higher performance? Do you ever change intake tract or exhaust components? Do you sometimes need to remove the idle mixture screw to clean the idle circuit on your carbs? Do you have trouble adjusting it while the bike is assembled and running?

Then you are in the market for an idle mixture screw adjuster.

There are a few on the market already, but none of them could work on my bike, a Kawasaki KLR 650. Two problems:

1. The idle mixture screw points directly down at the starter motor, not an inch below.
2. The best access is across the high exhaust pipe, so no short tool can save me from burning my hands, if the bike is at operating temperature.

How it works:

The main part is a small screwdriver bit with a special toothed wheel, which has a position-indicating slot machined into it. It is on the end of a long stick, and of course it can rotate. The other long stick has a hooked end, to turn the wheel by the teeth.

You just engage the idle mixture screw with the screwdriver bit with the hook, determine the starting angle of the slot, and use the hook to adjust by any fraction of a rotation that is called for.

Special warnings for idle mixture adjuster:

Caution: This is a precision tool. It is not designed or built to break loose a stuck idle mixture screw. If your carb is that gummed up, it deserves to be removed, cleaned, and rebuilt, with a real screwdriver. An idle mixture screw that is in shape for fine adjustment will turn fairly easily.

This tool is lightweight for ease of use and carrying. But it is also more delicate than your average steel tool. Do not pry, or use as a striking tool, screwdriver, or anything else. Such use voids the warranty.
