Help!!! 48' Bogging/Sputtering/Death
Hello, I am new here I have a 2012 48 that all of the sudden started sputtering/bogging down like its fighting for air or fuel. This only happens after about 10 mins when the engine starts to get hot and if i am going easy on the throttle just cruising. If i slam the throttle and ride like a bat out of hell everywhere I go it doesn't seem to be a problem. The problem is getting worse. I have only custom after market pipes and air cleaner only, no fuel controller. The bike ran finefor about 7 months and now..... POOP. I am and American living in Italy so HD dealers/maintenance areas aren't readily available. I have come accross some forms that suggested it could be a bad coil or temp sensor, IDK I don't want to troubleshoot by spending tons of money and just replace a ton of good parts trying to fix the problem. I just put the stock air cleaner back on because it seemed to run better before i switched to aftermarket..... Haven't ridden it since. Any suggestions would be greatly appreciated. Thank you!!!!

Buy a fuel pack, or XiEDs or something more expensive... You are not suppose to run an air cleaner without some sort of tune/pack. Hopefully you didn't mess it up already.... I know you are new here but before I did anything to my 48 I asked around and looked on this forum first before I made any changes to it to make sure it will be alright, good luck man.

Guys Im appreciating the comments and suggestions, I did do some research, and I must have been mislead, I thought the new Harley's were supposed to adjust themselves. Obviously now this seems like Ive been had. Like I said though i have switched back to the STOCK air cleaner, but I have yet to test ride it, I will however be able to give it the attention it deserves over the weekend, but now my work schedule is too rough. I will post any changes to the problem as I figure them out. Back to the topic though, does anybody have any suggestions of what would be causing this to happen NOW? I understand a fuel controller is necessary but If i did damage it any ideas on where to start looking for faulty parts?

From what I've heard you cannot run one or the other, you can run pipes but not just an intake. The only thing I can think of is internal. So you may have to pull it apart, but first ride it and see if its still doing it.

The new bikes can adjust themselves, but only so much. There adjustment range is about 7%, which is not nearly enough if you've added an A/C and pipes.

I have a 2012 Nighster, changed pipes (SE) and A/C (VO2), and mine runs perfectly.
I think you have got some bad fuel, or the tank's fuel filter dirty.
Had the same issues you are describing in another bike, and cleaning the filter fixed it.
There was some crud in there.

what you are describing is exactly what would happen if you don't add a controller...you bike runs in 2 modes open and closed loop...one is used during normal driving ie cruising down the road, the other is used during hard accelleration and when the engine is cold and some other times...so when you get on it it adds extra fuel making it run better, and during normal cruise it (because you chaged the intake and exhaust) runs lean ....you probably have done no harm to the bike..I would just install a fuel controller or some type, the xieds being the cheapest and ones lie the power vision being more expensive....if you are not going to do any more mods. to the bike I would go cheap ...
