Scottoiler

Scottoiler is a motorcycle chain lubrication system produced by Scottoilers (Scotland) Ltd.
Fraser Scott invented the Scottoiler between 1977 and 1983.
History
Fraser Scott came up with the idea when he was commuting from Glasgow to Manchester. Suzuki had released the vacuum fuel tap, and he was tired of the traditional method of removing the drive chain and boiling it in a pan of wax. The product has been available since 1986.
The Scottoiler has a valve operated by the negative pressure created in the engine's induction manifold, this is via the engines vacuum point.
The Scottoiler Vacuum System
Vacuum connections vary with manufacturer and model, for instance all modern Ducatis have a screw in the inlet tract which can be removed and replaced with a spigot from the Scottoiler kit. All multi-cylinder bikes have vacuum points to allow for carburettor / fuel injection body balancing so the Scottoiler is generally connected to one of these. In some cases a hole has to be drilled in the inlet tract or carburettor on a single-cylinder bike to create a vacuum point, this is not typical though and the vast majority of bikes will have vacuum pipes or screws.
The Scottoiler uses a Reservoir Metering Valve (RMV), which provides the flow control and incorporates the valve itself. The small nylon pipe from the top of the RMV connects to a vacuum point and the oil delivery tubing feeds from the bottom of the RMV to the rear sprocket delivery point.
The Scottoiler system is purely mechanical yet has no wearing parts due to use of air and oil with very few moving parts. If set up correctly the Scottoiler creates no mess, Scottoiler recommend feeding oil onto the rear sprocket face between 6 and 7 o'clock and having the drips set at a rate of 1 drip every 40 seconds.
A clean and properly lubricated chain can reduce friction and increase the life of chains and sprocket.
Add ons are available to enhance the Scottoiler but the basic system, sold as the Universal Kit is all that is required to lubricate the chain on ANY motorcycle, where necessary http://www.scottoiler.com/tools/write_media_resource.asp?id=764 are provided free of charge direct from Scottoiler.
A dual injector product is sold separately, feeding oil onto both sides of the sprocket. This is very neat and effective on some models of bike - however, the standard single side feed is capable of keeping the whole chain (i.e. both sides) properly lubricated - if you lube the chain lightly with an oily rag after heavy rain and after washing the bike. This ensures that the oil fed from the Scottoiler supplements the oil already in the chain.
The fitting instructions provided are full and comprehensive with illustrations. Filling and Priming the system require a special technique documented in the instructions.
As far as installation goes Scottoiler themselves are the best point of contact.
