I´ve made my own Scottoiler and it works superb.
I have to make the tutorial about how to make it but i can give you a few conseils.
Scottoiler is "cheap", well a 150€ in Spain... I´ve made mine for 50€ and the oil is so much cheaper.
You only need.
Time --> 2H
Material --> Pneumatic stuff as --> 1 caudalimeter, 1 electro-valve, wiring, 1 interruptor (in case it lubircates too much, wich actually does) and 3mm tube and you will have to do only 2 holes to the bike.
Mine works so well that a close friend asked me to install it on his BMW GSA800 and is as happy as I am. the transmission has 25000km on my Multi 950 and is in quite good shape. Almost 75% of the Km I do is with my wife and panniers... and riding not ultra fast... but fast enough.
I will post some pictures about it.
Sorry for my English.
