I've been using the Scottoiler on my last 4 bikes, 3 SM's and now a T 100. I have always hooked up the vacuum line to the port on the manifold, although I do not think it matters. All of my final set ups as far as position numbers have been different. The first worked best around 7, the second at 5, the third at 3 and now for some reason the one on the T 100 flows best at about 1 to 1 1/4. I did mount all of the SM's bottles on the chain guard and have mounted the T 100 bottle on the frame just behind the left side cover which makes it higher than the SM installation. I do not know if the height difference makes any difference, but it seems to. I have also been using the Dual injector on the last two bikes and that may have an effect on the flow volume. I do know I would not be without one, simple, fool proof and I think very efficent, and not nearly as troublesome as chain lubing and constantly cleaning the chain. I have adjusted my chain one time on the T 100 and that at 6,000 miles.
