Coughing Wideglide
I know the EPA has has really strangled my new engine, so I'm wondering if anyone with a new bike is experiencing the same things I am. When cruising at slow speeds it will occassionally cough, or when I'm waiting at a stop light with the clutch in and crack the throttle ( like we all do ) it will stumble. When I first got it, it would not even idle on its own so I had HD adjust it. I suspect the air screw needs adjusting for the coughing but I know the screw is capped. Should I just take it to HD ( and wait the mandatory week ) or can I remove the cap and do it myself without HD giving me a bunch of grief about warranty issues? OR, am I completely off base with this problem?

Usually, removing the cap over the idle mixture screw will do it if you don't have any mods. If you do this, get the bike warmed up and adjust it to the highest and steadiest idle mixture, usually found about 2-3 turns open after you LIGHTLY seat the screw. They are set very lean from the factory. If you do a SE air cleaner, and exhaust, you can go to a #46 slow jet and a #190 main jet (assuming this is a TC) and also open up the top of the carb and shim up the main jet needle with 2 -# 4 brass washers and your bike will never run better.
Just in case this is not too clear, here's a link that will take you through it, http://www.nightrider.com/biketech/hd_cv_mods.htm

The bike is stock with about 350 miles. Im going to have HD install the stage 1 soon anyway so I'm assuming they will iron out any carb issues. Thanks for the input guys.

RE: Coughing Wideglide
My bone stock FXDWG was doing the spitting thing.
It seemed worse in cooler weather. I cleaned the
spark plug first, because I knew I forgot and left
the choke on half choke one day and then I
re-gapped the plug with a tighter gap (still in spec)
and it seemed to help a lot. but it still does it
every once in a while.

>>>>>It seemed worse in cooler weather.
That's when it shows up more because it takes a bit richer mixture in cold weather to run properly. Try the above fix, you'll be glad you did.

RE: Coughing Wideglide
I'm not sure the problem is too low rpm. I have an 05 1200C that suffers from the condition you guys described. When I will be riding it from time to time it seems like it stops running for a split second then goes back (cuts out). This has happened under several conditions. When I have hit a bump, although not always when I hit exactly the same bump at the same speed. It has happened when I was cruising at 40-50mph in 3rd gear. I think too many people are experiencing this to brush it off as a shifting problem.
Sorry again, this was ment to be posted on "She's cuttin out.." but it seems to like to post it over here for some reason.
