Bear in mind that stock chains on most bikes are now of very poor quality compared to before or aftermarket brands.
I like that you pump the thing before riding. Scottoiler is a smart thing but depends on the oil's fluidity to adjust flow. It´ll flow a lot more in summer if you don't adjust it. I learned that when fitting a scottoiler to my Transalp and stashing the reservoir nice and out of sight under the seat. As soon as it got up in temperature from the engine heat on a longer ride it emptied all of the oil in 10 minutes and flung it all over the back of the bike, the back of my jeans and jacket. Cool stuff!
