[QUOTE="BigEd, post: 131945, member: 161"] My installation is the original vacuum operated version. The electronic Scottoiler gets good revues and I believe there are several other companies offering electronic chain oilers so they must be a good idea. Whatever method is used to deliver oil to the chain, some regularly is definitely better than non. Coincidentaly in the late 1980's when I was at university doing my degree course I designed and built an electronic chainoiler. I made a small peristaltic pump. (Simplistically it is three rollers going around in a planetary fashion, squeezing a plastic pipe. You've probably seen a larger version on a kidney dialysis machine.) I used a stepper to drive the pump and triggered it by mounting a sensor near the teeth on the rear sprocket. It was only triggered when the bike was moving and the faster the teeth went past the faster the stepper motor turned the pump. It worked fine on the test bench but I never got around to fitting it on a bike. Ironically my bike at the time was an 75/6 BMW .... shaft drive.:) [/QUOTE]
