Brought my wife's new 1200L home Thursday afternoon in 37 degree weather. Needless to say it was really cold. Had a 43 mile ride on back roads to keep the engine speed down. One thing I noticed that I didn't like was the poping once in a while. I ended up pulling out the choke a little and it ran better, but eventually it started to pop agian once in a while. Whats up with that? She'll have a heck of a time ridding it if that happens too much. I'll be mentioning it to the dealer next time I see them, but until then, anyone know what's going on???
Thanks

 

Congrats on new bike , Youll have to live with the popping or do some up grades. My 06 1200c did the same thing the dealer said ( its a Harley)

 

Is it a pop or does it sound like the carb is sucking for air? BTW congrats on the bike.

 

wow 37 degrees I guess i dont have to ask how is it hanging. As for the poping it dont sound right to me I would definetly get on the dealer for that one and dont take "its a harley" as a answer that is a blow off.

 

I don't know the "in the weeds" details but I know both my Sporties pop a little when its really cold. They did this more before taxes were paid. But even now, they aren't too keen on cold air. Once they get to full op temp they are better but can still pop here and there.

My guess: Colder air = more dense air. New hogs run lean. Denser air means more air into an already lean bike....lean = popping. Cold and lean = more popping than normal.

Take it out during warmer weather and see if it runs the same. If so, have them check it out. Nothing lost from taking it to the dealer.

 

The dealer actually explained it was due to emissions and how the bike is tuned. I put a jet kit, pipes and AC kit on and cured it.

 

Congrats on the new bike. I had a little popping on my '05 when I got it too. Didn't care for it but when I did my Stage 1, A/C, rejet and pipes, it went away totally. Bike runs much better now. Good luck to you.

 

Brrrrrrrrrrr… That’s hard core, bro. I hope she appreciated the effort (nudge, nudge, wink, wink).

I’ve never had muh Sporty ‘pop’, but then again I’m in Cali so it doesn’t often get that cold, and when it does it is usually raining so I cage it to work. Not because of the cold or rain, but because no one here knows how to drive…especially in the friggin’ rain. LOL…

 

I have an 06 1200 Custom with some pops too, mostly when trying to hold steady speed at lower RPMs. Dealer said to give it 1000 miles and try to stay within the break-in speeds (I'm trying, honest I am) and it would take care of itself. If not, even dealer said the stage 1 was the sure-fire cure. And, as already noted, it sure is a cold-blooded beast. Need some extra choke ("enricher") for several minutes longer than suggested in owner's manual. The 40 degree weather around here may have something to do with that.

 

Popping back through carb is due to more gas than air.
