Breakout conversion to 7" headlight
http://www.ebay.com/itm/361034589737
It's pretty much a direct replacement with a few caveats...
1. The bolt for the block that mounts it to the triple tree is NC Fine, so you'll need to purchase one - I think I used a 5/16x1.75 NCFine. (The original HD bolt is course thread)
2. The bucket comes with a harness, but it's easier to use the one from the original 5" bucket. You can release the contacts in the connector, then pull the wires back out and use the same rubber seal on the new 7" bucket. I cut the rubber on mine because I have an extra wire for the garage door opener sense wire to the Hi-beam lead.
3. If, like me, you have a windshield, you'll have to re-radius the opening for the new bucket. (Always fun cutting a windshield)
Here's a few photos.

1. More vibration because you have to remove the compensator.
2. More noise because your clutch basket is open now - clutch disk chatter is very noticeable, especially in neutral.
3. 3" wide is a bit too wide. Both BDL & R-P seem to have standardized on 2" wide belts unless you go to a competition setup.
4. PMI sells a BDL unit with their own covers for $1K more than BDL's or R-P's standard price. (ouch!... but it looks nice)
5. Changing to a belt will change the primary ratio. Here's the differences:
Stock HD chain: F: 34T R: 46T Ratio: 1.35:1
BDL Belt drive: F: 52T R: 69T Ratio: 1.32:1
Primo Belt drive: F: 49T R: 76T Ratio: 1.55:1
...So with BDL, you're RPMs go down a slight bit, and with Primo they go up a bit more. (I'm turning 3K at 70MPH)
6. The Primo gears are steel and heavy, but they slide onto the splines with no need for loctite on the splines (just like the original HD sprockets do). BDL tells you (and their videos show you) to smear red locket all over the splines. I had no idea why they said to do this until someone else said their gears are made of aluminum, which expands & contracts with the heat.
7. For any Belt drive primary, you have to reverse the stator oil seal.
8. The belt whines a little like a jet engine starting up when you get on it hard.
9. The change in ratios on mine caused the gear readout to become totally unreliable. There's a fix for this, but I haven't installed it yet.
10. Would I do it again? Hell yeah, but with the 2" belt.

Mounted under the Triple Tree using the headlight mounting bolt and the bracket that comes with the light bar. I ran the wires into my headlight bucket and used 3M vampire taps to ground and the Low Beam lead.
This helps during the day because of the sharp cutoff of the LED pattern.
