All chain-oiling systems promise to extend chain life and lessen maintenance. They all have their own interpretation of how to best accomplish this enviable task cleanly enough to improve upon the manual procedure. I once tested five systems of varying complication over a five-month period; hands down, the best one was the Scottoiler (produced in Scotland). And now Scottoiler has improved that original eSystem.
The new version continues the accelerometer metering that made the original eSystem so trick. No vacuum plumbing, no manual power up, no gravity feed, no oiling at idle. Essentially, the folks from Glasgow made their system intelligent. The self-starting electronic pump pushes oil only when it knows the bike is moving. No drool. It’s an elegant solution to controlling oil dispensation and is unique to Scottoiler. The accelerometer is now digital, which uses less power and allows more sophisticated control. In standby, the unit uses less than 400 microamps; under way, it uses approximately 3 milliamps and a bit more when the pump activates. No reason to worry about battery drain.
A new feature is a threshold adjustment that allows the rider to set when the system begins to supply oil. A normal setting initiates oil supply at 20-30 mph, although riders can now change the distribution threshold to suit their needs. This saves oil, adding a finer control over extra oiling and delays oiling in stop-and-go traffic. The display unit has been upgraded to automotive standards and is resistant to UV. Scottoiler has added a clock and a Fahrenheit thermometer to the display that augments the oil supply data and the G-meter.
Installation of the eSystem is the simplest of any oiler I’ve used. Attach the ringed wiring to the battery, route the display unit to a convenient area, and stash the reservoir electronic pump practically anywhere. Plumbing to the sprocket and dispenser assembly is unobtrusive. The kit comes with an assortment of universal mounting tabs, brackets, sticky-backed hook and loop, zip-ties and adhesive patches that should suit any motorcycle.
Programming the system is intuitive and well explained. Calibration is done with the bike upright and engine off. The system learns this static position and compares it to the accelerometer data when moving, then dispenses the proprietary oil at a preset rate. Mine is set for one drop per 60 seconds. If rain ensues, the rate can be altered quickly from the small control unit. Sweet. I used the single emitter as supplied; a double-sided one can also be had.
With the fine-tuning allowed by the pump timing, mess is controlled. A certain amount of fling-off is considered beneficial since it removes the debris that can quickly morph into grinding paste, but even that small amount can be eliminated if desired. I set mine to shed a small bit; our local roads are dusty and dry. You can dial in any amount you feel necessary.
As always, use care when installing any modifications on your bike. Installation is very easy, but chains and sprockets are unforgiving primitive mechanisms that can bite you or alter the safe rideability of your machine. Be aware of common sense details.
