air/ fuel mixture

My question is, Does the mixture screw , Meter air/fuel thoughout the rpm and throttle range or just low rpm and throttle. The reason I ask is ,My motor always runs to rich. I've opened the air box,k&M filter ,Big gun head pipe,supertrapp slip on,dyno jet, stage 3. you would think with all changes it would be more to the lean side. I just ordered the air/fuel adjustment with thumb adjuster.The bike runs great ,but I dont want to wash down the rings or contaminate the oil. I keep hearing about others saying there motors are cold natured. Mine will start in 20 degree weather without the choke. Thank Wayne 07 16000 smiles

Yep, I think you missed something. Cyanoacrilate (note the prefix) glue
(crazy glue) produces cyanide gas when heated. When you use an accelerant
or baking soda, it sets up very fast and releases heat and even a small
visible puff of smoke. That smoke is cyanide gas.
Advantages to CA glues:
. One-part system.
. Solvent free.
. Rapid room temperature cure reduces need for fixturing.
. Excellent adhesion to many substrates.
. Wide range of viscosities.
. Excellent bond strength in shear and tensile mode.
. Primers available for polyolefins and engineering plastics.
Disadvantages:
. Bonds to skin instantly, posing safety risks.
. Fumes are unpleasant and may present a health risk. (Produces Cyanide gas
when heated)

Wayne,
The key phrase is "dyno jet, stage 3." This will make your bike run
rich. Which main jet did you put in?
There is a LOT of overlap of the various circuits. I've seen the
spreadsheet someone published for generic carb's showing some overlap.
I've run a recording wideband sniffer. The main jet and needle affect
the idle mixture. The idle mixture screw affects the mixture at all
times - it does affect thing more at idle. I've worked on bikes that
came with the idle mixture screw seated, yet the bike would still idle
- although it did get hot quickly in traffic and surged badly under
part throttle.
Check the taper on the new mixture screw when you get it - it might
not match the stock taper.
HTH
all the best,
Mike
