Leak fixed but why?

84 R100S

So I'm finally out there riding my R100 after a lot of maintenance procedures. I've been taking short rides then inspecting my work. Today I was heading out for a longer ride (200 klms) and noticed oil on the shop floor under the swing arm. I checked the skinny hose clamps on the rubber boot and they were loose, though I'm sure they were tight when I re-assembled everything. So before my ride, I drained the drive shaft, and was down about 20 ml. I refilled the swing arm with 100ml of gear oil. My owners manual says it should take 150ml, but I have written a note to only use 100ml. I can't remember why I wrote this. Anybody know anything about this? So now I'm back from my ride and no leak. Should I lock tite the hose clamp threads? Bike is performing as it should, easily pulling red line, and stable on long downhills with hands off.

For clamping screws, I have never heard of any backing off and loosening.
Check them again in 1 or 200 km. If one or both is loose, lock tite.

I don't know about your note.

Duane was a proponent of less oil in the driveshaft as ok.
