I have an '07 road king custom. Put on rush slip ons and took out the baffles and added a screamin eagle intake(no remap). Am I going to burn up my engine by doing this? I like the way the exhaust sounds now but will change it back if I have to. Thanks
Get a Power Commander, or better yet, a ThunderMax W/Autotune.
You're going to do some damage, otherwise.

definatly need to get a tuner to get the air/fuel line where it should be

even after any remapping you could get a dyno test a piece of mind if anything.....................................

Old Skool no real bad backfiring, will get one when I get on it and then shift from 1st to 2nd also checked the plugs and still yellow looking. I just like the sound of not having baffles in. What do you think about the XIED by nightrider?? would that help any by richining the fuel/air mix?

What size baffles did you get? You can get up to 2.25 or 2.5 inch baffles in some Rush pipes that get plenty of sound, but also keep some back-pressure for torque. EFI bikes just don't perform as well with open pipes, no matter how you change the fuel map. For a bagger, you usually want to keep your low-end torque up there, especially if you're a big guy and/or doing any 2-up riding at all. I went with the PCIII and a touring bike map for my 2.5" baffles, but I got some bottom end back by changing the SE/Stage I air cleaner for a Doherty Power PACC. There are some others that will also outperform the SE, but the Doherty utilizes a small velocity stack under the (bigger) high-flow filter which smooths, layers and condenses the air flow in a way that is better for an EFI throttle body. (conversely, a carb will sometimes benefit from a vortex turbulence device to aid in fuel atomization)
For an '06 or later bike in particular, I'd probably just wait until I could pony up $$$ for the Thundermax, since you've already got O2 sensors. (mine is an '05, and would need bungs welded on)
Another step further would be to change cams to a high-lift, short-duration grind that would help boost the low end back up, and then mapping for that.

can't ass anything more, but get it checked out at least or you could have some high repair bills coming your way in the end.
