programmed with slip ons?
I just installed my slip ons today and the harley shop told me i would probably have to have it reprogrammed. He said it would cost $140. Is it neccessary with just the slip ons?

What slip-ons, SE or some other mfgr?
Some dealers/people will say yes it is, some will say no. But you will have to have it remapped if you replace the A/C with something like a SE or Big Sucker.

bobby5,
No,.... you wont have to rush out and get the download if all you added was a pair of slipons, but you will want to do that before you add a high flow air cleaner.

RE: programmed with slip ons?
I added SE-II slip-ons and did not do the download. The bike runs great and sounds awesome. My dealer told me I'd need the download but one of the techs said I wouldn't unless I installed a high-performance filter.
I checked the plugs after a long ride and didn't find them overly cooked (white). I get a little popping when I roll off the throttle at speed without pulling the clutch. Very little. I have noticed a slight decrease in gas mileage.
My goal was for louder sound for highway safety, not performance. I suspect I'll want the added performance eventually and will have to shell out the $$ for it.
Slip 'em on, give it a whirl and see for yourself.
Good luck!

Fact:
If you change the air flow in your system, (decrease the backpressure with slip ons will increase the airflow), and do not change the air to fuel mixture to compensate you will run your motor lean.
Fact:
Systems will compensate for the change. The compensation band is a plus and minus band range, 10 or 12%. If you force it to one end to compensate for the slip ons you will have no where to go if it needs more.
Fact:
Running lean can and will force the engine to run hot, burn valves, backfire, hesitate, and more.
Just my 2¢ on the subject.
