air/ fuel mixture

Post by Wayne Blackburn » Mon Mar 10, 2008 7:36 pm

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.

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
