Zdenko, regarding how oil delivered is determined by gravity, here is an answer to a "frequently asked question" Scottoiler used in it's instructions.
Quote:
Q: Why won't my Scottoiler deliver oil even when my reservoir is full?
A: "The Scottoiler is not a pump it is a gravity system, and relies on a head of Pressure between the reservoir and the end of the dispenser tube to work properly. This means the delivery tubing MUST be full of oil with no air bubbles, with the reservoir approx' 30cm higher than the nib for normal operation".
So this would probably explain why I may be dialed at a different setting to you for instance as I've just measured how much higher my Rmv (reservoir) is to the nib (chain oil applicator) and it measures 160mm above. Now 300mm above would have been ideal and I could imagine if that was the case my dial would probably be about 5 or so. Unfortuately I was restricted due to my wanting to hide most of the Rmv behind my rear peg holder. In any case it works fine regardless which is 1 - 2 drips etc etc.
So there you go matie, it is definitely a gravity system but for interest, as I have to top my rmv up later today, I will see for myself if by increasing revs it has any effect on whether more oil is delivered or not. I doubt it though just because the system doesn't work that way.
BTW when I put on my oiler, I also changed my final drive setup by changing to a top quality 530 size chain and sprockets and also put in a TBS rubber cush drive. Not that the cush would make much difference I don't think but it will be interesting to see how long the chain and sprockets last now with the scottoiler compared to before when manually oiling the chain.
