I'm not a "Brick K-bike" owner but have worked on a few. By "HID bulb swap", do you mean you installed an entire HID Projector like from Morimoto or just a bulb and ballast kit that still relies on the stock reflector surface to shin the light out on the road?
Unless you do the whole Projector install, you are not getting nearly the benefits of HID at all. They just can't get an HID bulb to function correctly in all the various myriad styles of headlights. The focal physics are all wrong and it's why they have laws about this. These cheapy half assed kits are what has given HID such a bad rep. Besides giving the rider bad lighting, they are diffusing the beam and blinding on-coming traffic even on low beams.
I did a complete custom install with a pair of Morimoto H-1 Projectors in my '08 K 12 S and the illumination is absolutely outstanding and on-coming traffic has no idea they are looking at an HID unless I forget to shut down the High Beams.
It is a lot of work and a bit of money but worth it to do it right. As you mentioned, the housing doesn't just come apart with the turn of a couple screws. You have to heat the housing in the oven to soften the rubber and very carefully pry the lens off. Then you bore the back of the housing with a hole saw, set the whole thing up while fighting the limited space in the housing and then find and build mounting locations for the Ballast, Starter, Resister, and all the wiring.
I had no problems with beam focus thru the stock lens of my housing. The shops that do these conversions for a living have no problems with the lenses on all the various makes of vehicles that they install them in so I'd say that is a non issue. I did all my own work but did have good advice from the shop that sold me the lights. They also said that 55w Ballasts are usually not recommended especially for Motorcycles and it's going to cut your bulb life in half. Personally, I also recommend avoiding all the silly colors and just stay with white. It's those colors that signal traffic that you are using HIDs and even if they are not being blinded by your lights, they have become conditioned to think they are.
I saw a post from some punk that bragged about running the purpliest blubs he could find and racing around with the brights on, blinding as many motorists as he could find. Yeah, that's just what the fuck we need; Ride around on this naked skeleton of a vehicle and piss off everyone driving 3000 lb. armored tanks.
Write me back if I can be of any more help.
