This is my 1996 R1100RT with 74000 km (46k miles) on the clock.

I bought this in March this year and the service history was not so good, frankly the oil looked really nasty.

With two short OCIs of 250 km each or so with cheapest available 20W50 mineral and then two longer ones with Valvoline VR1 20W50 mineral here we are today.

I have not used any cleaning products, just fresh oil.



 
What did under the valve cover look like when you first noticed the oil appeared black?
 
Sorry but I do not know as valve covers came off only after it was time to adjust valves.

Old oil was not just black but it was thick, nasty and smelly. First new oil I put in was blackish within first 100 km, second after 200 km or so. Then the color change 'calmed' down to normal levels.
 
Maybe you got to it before the goop started to harden so it cleaned out with good oil changes.
You obviously cleaned something out with those oil changes. Congrats!

Afterthought, I may look into Valvoline when my stash of Silkolene and Castrol runs out. But that'll be years (close-outs; Silkolene $6.29 a gallon online and Castrol synth on the AZ close-out table for $2.16 per quart last winter).
