idle issue

[koolaid_kid]

Will cutting that wire from the stator to the headlight to reroute it to the RR affect my headlight operation? I suspect not, but . . .

Not a bit. We always strongly suggest removing that loop and connecting all 3 stator wires directly to your R/R.

Back to the original question, an idle sag then settling up is usually an indication of too rich a mixture, as noted by BassCliff. Too lean can make the idle hang high. Since your mixture settings (post #6) appear to be on the lean side of the stock screw settings, is there any chance your pilot jets are a size larger than stock?

When you say "hang high" are you describing the opposite problem? Say come to a stop light, RPM might drop to 1500 for a few seconds and then return to 1000-1100? Or does "hang high" mean, just idles high? Trying to get my terminology down and I've heard a lot of people use "hanging idle"

"Sagging idle" is when the bike drops below desired idle speed momentarily say down to 500-700 rpm, and then comes up to proper 1100 idle rpm. This is usually due to too rich a mixture and leaning the mixture screws will cure it (assuming the pilot jets or air jets are stock settings).

"Hanging idle" is when the idle refuses to come down momentarily before dropping to normal idle rpm, or sometimes the idle never comes down. Hanging could also be much higher than 1500, perhaps 3-4KRPM. This is usually due to too lean a mixture caused by 1) air leak, 2) too lean mixture screw setting, 3) partially clogged pilot jet.

Of these two conditions, hanging idle can be harder to diagnose, because people start fiddling with multiple other settings to get it to idle when the pilot/low-speed circuit is not working right. For example, they might adjust the idle upward with the idle speed screw which is actually opening the butterflies, or the bike is running on the "enrichener" or "starter" circuit and they "can't get it off choke".

From post # 6

7) idle mixture screws set as follows #1 (1 3/4)#2(2 1/8)#3(2 1/4) #4(2 1/4)

One more thought, your idle mixture screw settings appear to indicate that you should be on leaner than stock settings (typically 2.5 turns), but the "idle sag" says too rich to me.

If your pilot and air jets are indeed stock sizes, then it is possible that your float level is too high and you might try adjusting the floats downward.

idle issue

I'm almost certain i discovered the cause of the idle issue. A week ago i changed a rear tire due to picking up a nail . The exhaust had to be removed slightly to remove the tire and to re-torque the axle nut. I torqued the exhaust to the head but failed to tighten the exhaust bolts to the mufflers.I have not had a chance to ride my motorcycle due to rain but I"m hopeful this is the cures the problem.
Thanks for all the suggestions of fellow members.
