Air Mix Screw/Knob

I pulled my carbs off today and accidentally broke the threaded end of the idle/air mix screw/knob... Any idea where I can find a replacement at? Perhaps one that would cost less than buying from Kawi?

1990 VN750
Got it on 9/10/09
7683 original miles when I got it
7870 current (constantly adding more)
Mods already on bike:
Kuryakyn Iso Grips with throttle boss
Kuryakyn Iso pegs with heel rests
Windshield (not sure what brand or style, just look at my pic)
Leather Saddle bags
Leather t-bag
Mods since I got it:
Wet Battery
Many more to come...

Cheapcycleparts.com calls it a Screw-Throttle Stop... It is a knob that comes by the rear carb, a few inches aft of the pet cock, that you twist to make the idle richer or thinner... The threading end is what broke, but it is one whole piece, so, I need the whole new piece to replace it.

The manual calls it the "Idle Adjuster"...

All that knob does is adjust idle speed, not mixture. The pilot screws adjust the mixture. The thing to do is get a whole new unit from cheapcycleparts or bikebandit. Jerry.

I am a motorcyclist, NOT a biker.
