Can anyone tell me of a fix?  I beleive I have a carb freezing up due to cold temperature riding but before I get too involved in it I was wondering if anyone else knows tis problem and has a solution already.

While riding at interstate speeds at 30'ish temperature my bike runs fine.  But when slowing down or after exitiing the bike will choke and sputter for about 10 minutes.  After that all is well.  I am assuming this is because of something freezing up once consistent flow slows down until it warms upa gain?  Carb?  Fuel line?  Any thoughts?

Definitely sounds like carb ice to me. An old timer's trick is to put a piece of cardboard or other type of wind break on the forward side of the carb. This keeps the direct wind off of it and also sucks some heated air up around the back of the wind break, warming it up a little bit more.

What kind of bike?  Knowing the orientation of things on it might help a bit.

Used to fly an old 150 Cessna a lot that for some reason had a propensity toward carb icing.  There just changed altitude.  That may not work with the bike though ?

I could see where the bike type might help.  '04 Lowrider with the Screamin' Eagle air intake.  I added a pic.

I was thinking about a simple fix like cardboard  or a leather wrap of sorts but want to make sure it's not something else.

If nothing else has been found, and it only does it in the cooler weather, it certainly sounds like carb icing could be a possibility.  Wrapping the carb or changing the air flow around it are all old tricks to deal with it.

Did it happen to start at any time coincidental to the installation of that air filter assembly in the picture?  Venturi effect down the throat is going to lower temps.  If that air cleaner just happened to let in a bit more air the venturi effect might be just a bit more.  Sometimes those "bits" are just enough to make a difference.

I responded because I had the very same problem riding to Daytona in '03 or '04.  When I left here, it was slushy wet everywhere, so the humidity was high. The old rule of temp and dew point spread of less than four degrees came to play that day. Everything was fine running down the highway as you mentioned. BUT! As soon as I hit a traffic jam getting out of town, damn thing just conked out at 60 or so. I got it going before having to stop, but it took a lot of throttle action to keep her runing. Once I got out of the traffic and got back on the cruise at 70 or so, no problem. It came back when I stopped for dinner, same thing. It repeated itself everytime I came off the cruise to slow down. At that time, I didn't know how to address it.

It was in Daytona when an old timer asked me about the ride and I told the story that he said it was ice and told me about the cardboard. I've never needed to use it again, but if it happens again, I'll know what to do.

Chuck, you'll never have to worry about ice on the butterfly nor anywhere else in the inlet.  Those 110s run so hot they are self de-icing!

I may be a bit slow, but I'm beginning to think you're making fun of my motorcycle.

No man, not at all.  That's a beneficial system man.  Check in the owner's guide for "Anti-icing: Parasitic use of dumbassed levels of heat generation for icing prevention."  It's there sir; really!

I guess it does do away with having to apply carb heat on approach, so that's a benefit.

H/D marketing just read this thread & plans to add:

2009 NEW Accessories - 110 engine reflective shroud deflector for additional furnace type heat in those cold winter riding months. $495 (also requires $39.95 hardware installation kit).

I admit the air cleaner is a contributing factor.  After I took the "football" off it did get worse.  I will proceed with trying to wrap the carb and see if it is possible to get some airflow from between the cylinders up to the carb.  Most of the time I am riding my SEEG in this weather and the Lowrider is a summertime thing but the bagger is in the shop right now.

No surprise that the air cleaner seems a contributing factor.  Just looking at it gives the impression that it might.  Hopefully the bagger is home soon or the humidity or temps will work more in your favor.
