SOURCE: setting the timing 2002 road king fuel injected

Your bike's timing can only be adjusted through an interface to your ECM like the Screamin Eagle Race Tuner. Have you made any changes to the exhaust or intake? Have you added and aftermarket item like a Power Commander? changes in these areas could account for the problem you are having. hope this helps.

SOURCE: 2002 road king horn wiring were due both leads connect to

I am assuming you mean what are the color of the wires that go to the horn. If so, the yellow/black is positive when the horn button is depressed and the black is ground. The wiring for the horn button is orange/white positive and yellow/black to horn. The orange/white wire gets 12vdc from the acc fuse.

You will have to measure your tire width and the frame width for the rear tire as Harley went to a wider rear in 2007

I took the baffles out of my harley 08 streetglide it runs lean what to do

The ECM needs to be reflashed with a new map that represents your new system but I doubt there is any may out there for NO BAFFLES so you likely will have to get to someone with a dyno and have a map created and flashed to your ECM.

Back fire with vance hines pipes

Sounds like it is running lean. The ECM must be remapped for a performance breather and/or free flowing pipes. I would use H-D Super Tuner or have a dealer do a digital download to remap the ECM properly for the changes you have obviously made. You may do great harm to your engine if you run it without the mapping change as the VE will be changed and the ECM doe not know what is physically going on with VE if it is not mapped into the ECM

I hope you are speaking of the ECM, otherwise my advice may not be of any value. First if you have any modifications to the bike such as pipes & air cleaner, etc. then your issue would be magnified. The information in your "computer" as it relates to how the bike runs is called a MAP. The map defines idle speed, desired air fuel ratio (AFR), rev limit, monitors O2 sensor information, and much, much more. So if the MAP is say for a stock bike and yours has pipes, etc. then it will run poorly. I would call the dealer that replaced the part for you and ask if they downloaded the right MAP for your bike.
Without special equipment (i.e Screamin Eagle Race Tuner SERT) you cannot make changes yourself.
Please start with the call to the dealer and please post your results for us. Thanks and hope this helps.

2008 FLHRI, what spark plug numbers for the different brands would work in my bike? Would even like to go to a little hotter plug if possible.

You would be best to stick with the factory stock plugs. A hotter plug will make the engine run physically hotter, not "hotter" as in "faster." Only go to a hotter plug if reading the current plugs indicates the need.
