Can anyone tell me what i need to do in order to run Kuryaken Crusher slip ons without causing a lean fuel situation? Ride is an 05 ultra classic fuel injected. I want to upgrade my air filter element as well.....since im pretty inept with a wrench, should i be looking at a fuel mgt. module install by a mechanic or should i get a stage 1 download from my dealer? I honestly only wanted a better sounding exhaust but a little more horsepower would be great....

Thanks for any advice!

 

No matter what you do to change the sound of a motor, it will change the tune. Just remember that a motor is a big pipe organ. Nobody can say richer everywhere or leaner everywhere but it will be different.

You will need to change the fuel/air mixture for your bike with those changes. Your bike is lean from the factory for emissions and by adding more air (freer flowing filter-exhaust) you will lean it even more. The decision is yours on which way to go but thinking ahead is helpful. More mods later? ....something that has more tune-ability. Stock as a rock until gone?.. flash would be fine. Many dealers will cut you a break on the flash if you buy the parts form them.

 

The dealer download will still have the motor running lean but not as bad as without it.
The easiest and cheapest fix would be to install an XIED. You just plug them in to the O2 sensor wires and you're done. They fool the ECM so that it adds more fuel to the mix.

What do you guys consider lean?

Keep in mind that the difference between 14.7 and 14.4 AFR is only 14.7/14.4=1.021 or 2.1 percent.

the xieds are 13.8 and work well for stage 1 plus they are very easy to use, ran them for a year and a half and was happy

 

Nightrider says xied not available for my 05? Maybe no oxygen sensors on 05s and earlier?

 

Hate sounding dumb but what is "flash"?

 

I "flash" is having the ability to change the EFI fuel and ignition maps in the stock computer that runs the bike. The devices/software that can do that in the Harley world runs from about $500 to about $800 depending on the options you are looking for.

Hope this helps

Thanks guys. Decided to bite the bullet and order the fuelpak and a big sucker to go with the kury crushers....any good videos on the fuelpak install?
