The oil is simply siphoned from the reservoir by gravity, the engine vacuum provides the power to open the valve and the dial at the top allows you to adjust the flow rate by opening/closing the valve aperture.
Check out the Scottoiler technical section to find out in more detail how the motorbike chain lube system works.
The range on this kit is up to 1500 miles (depending on flow rate, speed, etc.) between reservoir refills.
All Scottoiler motorbike chain oiler kits use our own specific oil developed for application through a motorbike chain lube system. Our oils have a low tack additive to ensure dirt doesn’t stick letting the oil work on lubricating and protecting from corrosion.
