My street bob is sick and needs some help. I upgraded the intake to the Screamin Eagle force air breather and downloaded a map from Dynojets website that is a similar (close but not identical) setup as I have on my bike for my PCIII.

I've now noticed it pops a bit on decel.. which i didn't have before, and my force air breather thingy (90 degree chrome elbow with expsed filter) gets warm-hot when I ride. Anybody know why?

Dynojet people suggested perhaps leaning it out 2 bars midrange and 1 bar lower range if I recall correctly for the popping, but I just noticed intake getting hot.

Anybody had this happen?

It's an 06 St Bob, with V&H sshots staggered, the SE force air breather and PCIII...

If a dyno isnt a option I would try a few different maps for similiar type set-ups and see if you can get rid of the popping that way. if that doesnt work you can try adjusting the closest map.

As far as the Breather getting hot it depends on how hot. Mine gets pretty warm but wouldnt call it hot. It is warmer than the stock air cleaner was but you had some plastci inbetween the metal on it.

 

MAn if it just " pops a bit" why worry if it otherwise works fine ie no overheating no power loss issues stumbling etc then leave it alone I mean for FS its a Harley.

 

I had to add fuel to the closed throttle position on my map to get rid of most all of the popping on decel.

 

as far as the breather's temperature.. it's pretty darn warm, but you can touch it without getting burned. Just a concern since the stock one doesn't seem to get warm at all.

As far as the popping.. I appreciate your laissez faire approach Steelcowboy but I want this bike to last me a long time, and that normally means keeping it running right.

Pig, I might try that. BTW, I've never tried adjusting the PCIII with the buttons on it, just by hooking up the laptop, anybody out there done it? IF so, how? I cant find any instructions and I've had it for so long I can't find any of my papers on it..

 

Look on Power Commanders site for the instructions on the buttons on the unit itself they are there somewhere. I myself don't use those buttons, I just program the map with the laptop.
Try this and if it doesn't work you can always put it back to the way it was and it won't damage anything...
On the map you have try adding 10 to whatever numbers are already there in the 0% throttle position (probably all zeros) from about 1500 rpm up to redline. See if that helps or no makes the popping worse then you know which way to go. I had to bump mine up to 20 and almost all popping was eliminated. I still get about 50 mpg on the highway too so it's not like it's wasting a ton of gas.
Let me know if that helps.

Of course you can always go get it tuned at the dealer for mucho bucks but adjusting the map yourself takes 5 minutes tops and is free and ain't gonna make your bike explode unless you do something really ignorant.
Hey Vdub I have a SE air cleaner (not the same one you have but close enough) and short shots also. Fuelmoto sent me a map that was programmed for a SE air cleaner and short shots and I can send it to you if you like. I use that map on my bike but like i said I adjusted the 0% throttle position to add 20 from 1500 rpm to redline to reduce popping.

 

Its not spark knocking its popping which is nothing more than more feul being added than its burning. Which means its rich. It doesn't take a rocket scientist to figure that out. Our does it? Either way explain to me how that will shorten the life of the bike? Maybe you haven't been around bikes very long I dunno but I can show you a pile of Evos and TC that ave popped since new and are 15 years old plus. They seem to be doing just fine. BUt then again maybe yours is special....

 

Piginablanket, if you could email me that map I'd appreciate it.

Steelcowboy, I apologize for wasting ur precious time with my post, I am not a rocket scientist and I'm sure NASA doesn't mind u helping out a taxpayer like myself with such a trivial issue since u apparently are. I also am sooo sorry u pointed out that decel popping = rich, which apparently I didn't articulate that I previously understood, which would have saved u the time of typing it. What I did articulate is that i have decel popping (which means rich even though the modification i made (adding force air breather) shoulda made it lean. That coupled with heat emanating (may not be spelled correctly, I'm not an English professor either) from the intake tube caused me a bit of concern because I had neither prior to the modification. And if u don't understand the consequences of running too rich or too lean, "Either way explain to me how that will shorten the life of the bike? Maybe you haven't been around bikes very long I dunno but I can show you a pile of Evos and TC that ave popped since new and are 15 years old plus. They seem to be doing just fine. BUt then again maybe yours is special.... " maybe I'm horribly mistaken in believing that a fuel/air mixture affects both performance and wear on the engine components and I'm a total idiot for thinking it's silly to try and keep the bike running at it's best.. I guess I just don't want to have a "pile" of bikes. I like mine standing up in the garage just fine.

Appreciate the help/suggestions from the rest of the gang on here, not the condescention and sarcasm from someone who thinks anyone who hasn't "been around bikes very long" (which I don't know how that means anything since I know people like my wife who has been around cars her whole life but doesn't know how many spark plugs her engine has or where they're found) is a moron. You're obviously a bit arrogant and a supreme master of all things motorcycle and I'm sorry for troubling u with my issues ... feel free to refrain from reading my posts in the future.
