I decided to give one of these automatic oilers a try. I purchased the vacuum operated, Ducati red version. As we all know, red would be the best.
It took me while to decide if I wanted to have some gonkus monstrosity strapped to the frame with zip ties and exposed tubing. I was afraid of spoiling the look of the bike. So far, I'm good with it.
Here in the US, we get a bonus canister to collect fuel vapor. It's the best place to get to a vacuum line to open the oiler while the bike is running.
That pic is just below the tank on the left hand side. The kit supplies a tee fitting. Just need to cut the vacuum line to the canister and PCV valve from the two intakes, insert the tee, and tube everything up. A dampener is supplied (small black "L" fitting in the pic) to source vacuum for the oil tank valve.
I tried to be as discrete as possible routing the oil tube to the rear sprocket. The kit has everything you need to set up the applicator.
It works as advertised. I commute 500-600 miles per week, and I'm hoping this helps me keep the chain in top shape.
