I called the dealer and asked them if I would have to have my bike remapped if i installed a set of slip ons..... she said I would need it remapped, and i would need to add a new air intake....... the bike is fuel injected.

Is her info correct? she said the bike would run rich if i didnt have it remapped

 

The info is not exactly correct but it is recommended. Prior to 06 you could change your pipes without remapping your ECM. The 06's are already so lean that many of them don't run correctly stock. If you change anything at all it makes a difference on these bikes. If it were me I would do the intake and pipes at the same time. Don't even consider the download from Harley. Have them install a SERT (Screamin Eagle Race Tuner) or Power Commander (PCIII) so you can tune the bike properly and get rid of all the lean conditions caused by the EPA.

 

First time I've ever heard of a bike getting richer with a Stage 1

 

Yes. Think of it this way...

You are opening up the exhaust so that the engine can "exhale" better. You also need to open up the intake so it can "inhale" better. The reason it may tend to run rich w/ pipes and map (but now Hi-Flow filter), is that fuel delivery is "adjusted" (increased) but the bike physical ability to suck air in has not changed. THe result "can" be more fuel than air - proportionally speaking...

You really need all three.

The mapping can be accomplished a number of way: Stage 1 flash on ECM, Power Commander, S/E Race Tuner. Stage 1 is cheaper, but less precise and far less flexible.

 

Thanks fellas,,,,

my bike is an 06 standard fuel injected....... guess i'll just wait till i feel like spending a lil more money and get the air intake/pc all at the same time......

i was trying to accomplish a deeper sound for only a few hundred bucks-- looks like its outta the question

I tried just the exhaust for sound even though I had the SERT but was gonna wait until my 1000 miles before dyno tuning. My bike backfired and ALOT of popping on decelration. I would not recommend doing just the echaust unless you plan on doing it for a couple weeks until dyno tuning.

 

Ditto!

 

I agree! If you are doing a performance package, make it includes new exhaust (or mufflers), Stage I air intake, and either PCIII or SERT. I have SERT and Rinehart Tru-Dual on my RG. Before the dyno, it backfired and popped all the time. After the Dyno, not only the pops, pings, and backfires were gone, I also gain over 30% in torque and horsepower!

One note: don't get suckered in by an HD dealer that you need to have Stage I download done. That's a waste of $150 you don't need to pay! All the download does is allow your engine the ability to go to 6500 RPM, before the safety cut-off. Stock engine will go up to around 4400RPM before cutting off.

Spend the money and do the Dyno! You'll see the difference!
