Here follows my opinion about the Scott-oiler (or every other thing that
works the same.)
How works a Scott-oiler ??
Driven by vaccum in the carburator the Scott-oiler now and then releases
a drop of oil above the chain.
On which link of the chain does it drop ??
Nobody knows.
Because the Scott-oiler drops quiet random, you never know on which link
the drop lands.
5 Years ago I wrote a little programm that simulates a Scott-oiler to
test the use of it.
-You have to tell the programm how many links a chain has, 124 in the
case of a Twin.
-Then the programm simulates the falling of drops on random links.
-When every link is hit, the programm tells how many drops were used.
-After about 100 calculations, the average amount of drops used is about
600.
This means that you need about 600 drops and then every link has
received at least one drop.
But there are several links that got more drops.
How many drop are there in one fill of the Scott-oiler ??
So you see.. You are not sure that the chain is always well lubricated.
And there is always a ( verry little ) change that there is one link
that never will be lubricated.
But, the chain looks verry well oiled some of you will say ...
This is because a drop oil lands on a moving chain.
The chain moves on high speed with a speed of more than 14 meter/second.
How the f**k can a drop land on that chain and have the change to
penetrate between the link-plates before it gets 'airborne' again ??
It is splattered around worse than a bug splats on a helmet of a
blackbird-driver. :-)
It has to be quite tacky (sticky) if it wants to stay on the chain.
But if it's that sticky, it will not leave the thin tube of the
Scott-oiler.
So my opinion is that the name of a Scott-oiler better could be:
Rear-wheel / environment oiler.
- Years ago Honda experimented with a kind of auto-lubrication of the
chain.
They made holes in the front-sprocket and lett the oil leave the
sprocket to get right on the chain.
- In the motocross they used a kind of Scott-oiler that was driven by
the rear schockabsorber.
If this were good ideas they could still be found on the bikes
today.....
But I don't see these principles around anymore.....
Personaly I prefer spraying the chain with a desent chain lube, like
from DID.
It's high rated in a German motocycle magazine who tested different
chain lubes..
At our club (Transalp Club Nederland) some people experimented with a
Scott-oiler.
The told that their chain lasted about 25000 Km.
If you think that it's long then I must dissapoint you.
On my last Twin the orriginal chain lasted 45000 Km, and I can't say
that I drive slow. The bike was even tuned.
There is one case in which the Scott-oiler has advantages and that's
when you drive far away from home in the desert
and don't have a centre stand. But how many people of us do this often
??
But as whith all apliances and accesoires everybody has to decide for
themselves if they can use it.
And of course everybody has different conclusions (opinions).
By the way : That's what life keeps interesting and far from
boring.......
