Sounds neat. They should have a great time with it.
Couldn't see your pictures, though. I went to your profile, but they say "Locked"... Maybe try hosting 'em on Photobucket and linking 'em to here.

Yes. Post your question in the XL175 section, and someone'll answer.
Welcome aboard!

Great job!
What am I looking at here? I guess I'm a little slow on the uptake, but I can't tell what the original manifold should've looked like, nor where your repair is.
Can you take another photo, maybe backed away a little bit?
I feel so foolish....

The adjustment is a screw threaded into the end of the rocker arm. The screw is adjusted in or out to increase or decrease the clearance between it (the screw) and the end of the valve.
This adjustment is done at top dead center (or thereabouts) on the compression stroke so you're sure the valves are fully closed, and the cam is not trying to lift either valve.
The screw is held in place by a lock nut. Loosen the lock nut, adjust the screw, hold the adjustment fixed and tighten the lock nut. Tightening the lock nut will tend to move the adjuster too so you kind of have to hold it fixed with a screwdriver in one hand and tighten the lock nut with a wrench in the other hand.
The clearance itself is supposed to be set using feeler gauges. You insert a feeler gauge (a thin piece of metal of an exact, known thickness) into the gap and tighten the adjuster screw until it just creates a slight drag on the feeler gauge when it's inserted/removed.
Intake valves on our vintage Hondas typically run with 0.002" ~ 0.003" clearance and exhaust usually runs 0.003" ~ 0.005". Your specific year/model may vary. You'll need to look it up somewhere.
And that's about it.
Good luck with it, and keep us updated.

Oh, MAN! That is just fanTAStic!
I'm really impressed.
I think I need a cigarette..... :)
Thanks for the update and the idea. I've seen those motors available pretty durn cheap.
Again, looks great!

Yeah, the 80s vintage XL's no longer had points, so you'll need to go with the CDI wiring description...
Good luck with it,

I'd start by looking at the shift linkage inside the clutch cover. Pull the clutch cover and see what's up. Any loose bits? Any worn nubbins on the shifter 'star wheel' thingy? Is the little roller thing loose or not riding on the edge of the star wheel?
Then, trying shifting while observing that linkage. See any obvious hang-ups?
Good luck,
Kirk
