Had a Scottoiler for the last 6 years on 3 different machines. That would be my recommended first addition to any chain drive streetbike. Dialed in on 9 and getting a drop a minute? Sounds like you may either have a kinked line, or maybe not hooked in to a vacuum port. The first time I installed one (on a Trident), I was getting less than a drop a minute and thought the system didn't work. With research, I had not gotten a vacuum port so the valve in the reservoir never opened. Mine is tapped into the carb port just above the TPS on the right carb. At the lowest setting, the oiler is doing very well. The reservoir is mounted to the frame behind the passenger peg holder, and the tube is on the bottom of the swingarm just in front of the sprocket. If you take the vacuum line off and... don't laugh... suck on it, it doesn't take much vacuum to open the valve (and make sure it's the vacuum valve, not the delivery line), oil should flow. If it doesn't, go through the Scottoiler troubleshoot list. If oil flows, you know there's nothing wrong with the system.
