Default popping on decel

Hey guys, here's the run down I recently installed a cycle shack slip ons and the x14ied. Ran great but the engine was so hot in the afternoons when its 70+ out and your sitting at an intersection. So I decided to order a dk customs 425 ac. Installed it this morning, took the bike to work. There was some popping on decel when i first left the house (engine wasnt warmed up yet) after a few miles it seemed to get better but there was still a very slight popping.

Would you guys recommend? going to a xied or vied? I want a power vision but my wife will kill me if I spend 500 bucks right now

I had the same issue. I ended up buying a Power Vision though and it worked great. I'm not sure if buying xied or vied would help enough to warrant the cost. That's money you could put towards a Power Vision.

Check your plugs, if there good don't worry about it. I'm running xieds and the bike runs good. no popping.

i also run the xieds and no popping at all


this is direct from dk customs website

A Technical Update:

The 2012-13 XL's , especially the 883, seem to do a bit better with the XIED's.
HD has changed the fuel maps due to emissions regulations. This has resulted in the 2012-Up sportsters really liking the extra 2% fuel the XIED provides over the X14iED.

Not that any of the 2012-Up XL's will run bad with the X14's, they just respond better to the slightly richer XiED's.

I plugged the plugs and they do not look good. Deff running lean. I pulled the fuse to reset the bike and maybe the ecm will adjust itself. If not I'll see if I can return the x14 and get the xied. I asked nightrider and he said the x14 was better for the iron but perhaps I need the extra 2% with the ac. I'll take it to work tomorrow and see how it goes.

I think when you talked to nightrider he may have misunderstood you. The 2012+ Sportys definitely do better with the XiED's than the X14's.

With the cycle shacks you may have some decel pop no matter what, they are a pretty open pipe.

You can try the Thunder Torque Inserts, they may reduce/eliminate the pop, but they will definitely increase your low and mid range power, so at $25 they'd be worth it anyway.

Update: took it to work this morning, 8 mile ride and I can tell its running better already, i guess pulling the fuse worked. very minimal popping, throttle response is better, engine is cooler. I will see how it goes, I really want the power vision tuner so I may buy one in the next few weeks...

I pulled the 30 amp fuse in the side panel, depending on your bike it may be bigger than 30 amps..

In case anyone wanted to see what the 425 intake looks like...so much smaller than the stock ac!
