First he'd pre-empt future issues by fitting a fuel filter, cunningly using twisted garden wire to clamp the lines:
Mind, he'd have to cut the fuel line carefully to get the filter to point slightly downwards, or else he might not get enough fuel through.
Then he'd take the headlight off, and discover this rat's nest of cabling. This is going to be an Issue later, he'd think:
He'd then replace the standard bulb with the aforementioned 50W/50W 7500K blue-white Xenon bulb, and then he'd compare the before and after brightnesses and colour:
I bet he'd be pretty impressed with the difference!
But then he'd notice that - oops - the new bulb has the dipped and full beam reversed, so that dipped produces a (vertically) higher beam than full. What to do, what to do...
He'd check the bulb, and discover that it has anti-Murphy's Law tabs that stop it being inserted the wrong way - or perhaps the right way in this case. So he'd nip a bit off one tab and reverse the bulb.
Or would he? Well, perhaps not, because he'd likely realise that this would throw out a bad light pattern. Those of us without a scriptwriter have to find that out by trial and error. Most likely he'd skip straight to putting the bulb back in the way the fitting wants it, then unbolt and rotate the whole headlight 180 degrees, wilfully ignoring the "top" and "bottom" markings, and fit a small greased bolt through the lower drain hole which is now at the top.
Hmm, he'd say, that seems to be better. The dipped beam is throwing a lower light, but a broader spread, which might be wrong, but is likely to make the bike more visible from a wider angle to the front, which is the goal of the current exercise.
Then he'd shrug and leave it for now until he could figure out whether there was another type of "BA20D" bulb, although there doesn't seem to be. It's a puzzler.
Finally, he'd perform some rubber mallet adjustment on the crash bars for a Jinlun 125 RS to narrow the lower mounting brackets very slightly, and discover that they then fit the Huonaio just beautifully, bolting through the upper of the two existing bolts at the bottom of the frame, then clamping neatly to it without pinching any cabling.
Result!
[UPDATE]
In the re-edit, MacGyver had a crisis of confidence about the headlight. Suddenly, he was struck with a blinding flash of the obvious! Quick! Back to the MacGarage!
With one - OK, two - manly spins of the socket set, the headlight was rotated back to the correct orientation. With the new bulb still in the "right" way round, the dipped and full beam settings produced exactly the opposite of the desired lighting.
The solution: just mentally reverse the switch, i.e. ride with the switch set on "full" beam.
[UPDATE to the UPDATE]
Then he'd realise that he could just swap the two bulb wires over. Amazingly, they're actually solidly soldered to the contacts, rather than just being spaded on, so he'd have to cut and strip the wires and then use a bit of chocolate-block to swap them over. On the bright side (pun fully intended) that will make it easier to swap them back in future, as well as making it fairly obvious what's been done.
[UPDATE to the UPDATE to the UPDATE]
In the post watershed edit, MacGyver swears like a wounded pirate as he realises that if he'd just traced the blue and white wires from the bulb up past the wrapped section of cable, he'd have found two plugs that can easily be switched over, without the need to insert or modify anything.
I think that now officially makes this bike "custom": PROPER JOB.
