Snotoiler

The only bike I've owned with one is the FZR and I've hardly ever used
it so I'm not basing my views on that one. Adies old 595 used to leave
a marker wherever it was parked as have a number of other bikes I've
looked at.

If I used a bike to commute on for 12 months of the year then I might
have a different opinion about the whole issue but for anyone doing
around 5k miles per year they're a waste of time.

 

Care to explain how your Scottoiler varies its delivery rate
other than off and on, where the on rate depends on the position
of the knob on the reservoir?

 

It used to drip, till I primed it properly. No air bubbles in the tube,
no drips.

Bollox, next it'll be fixing hand grips.

 

It's connected to the vacuum pipe on the carbs (or throttle bodies).

If for instance your oiler dribbles one drop every 20 seconds
irrespective of speed. Then the chain will be very much over oiled at
1mph, but under oiled at 100mph.

The amount of oil dispensed needs to be either related to the speed or
the mileage being done. The lubrication also needs to be independent of
the temperature and viscosity of the oil and the only way that can be
achieved is with a pump, not gravity feed.

I will agree they are cheap, reasonably easy to fit, but that they can
be improved upon and that there are better ones around.

I will certainly agree that they are better than no oiler at all.

 

Pip expressed precisely :

Not quite...

Usually high rpm will mean high speed, will mean wider throttle opening
and LESS manifold depression. A high manifold depression (greater
vacuum) occurs at tickover and even more so under engine braking
conditions.

 

I don't know about your chain, but mine goes round and round.
Irrespective of speed, my chain gets the same amount of lube.

Scottoilers aren't gravity feed. Viscosity does make a difference but flow
is easy to regulate.

 

They are gravity fed (or wouldn't have a breather), they just use an
on/off valve that's vacum activated.

simple, but effective enough.

 

Oh. OK. That's me put in my place. I must read the instructions one day.

Yers.

 

mb explained :

Don't you think more oil with greater distance covered would be a major
advantage?

Mine is easy to regulate. I set it when I first installed it since when
it has never needed any further regulation or attention at all.

 

mb brought next idea :

So far as I am aware a Scott oiler does use a gravity feed system. They
have no pump, relying entirely upon gravity with a vacuum operated
valve to simply turn the thing on. So temperature and the viscosity of
the oil will have a major effect on the amount of oil delivered.

 

Oh, hang on a minute, weren't we talking about speed?
And yes, it does get more oil with greater distance. You haven't thought
this through properly, have you?

Super. I'd rather have a simple Scottoiler than an overly complicated pump
and controller *and* sensors. But that's just me.

Speed is distance. The faster you travel the more distance covered the
more frequently the chain needs oil.

Proportional to the distance covered, I think not not. It just dribbles
the same amount of oil irrespective of whether you cover a mile a
minute or one mile an hour. You start the engine, the oil flows at a
fixed rate until you stop the engine - how useful is that?

 

Why would the chain need oil more frequently? And the chain *does* get
more oil the greater the distance.

See? I said that already.

Of course it does! More distance = more oil. That's called proportional
where I come from.

Very useful. Don't you remember what I said about my chain going round and
round?

Go away and think about this some more. You're just not getting it.

 

Harry Bloomfield says...

Very, if you can;t be arsed to get on hands and knees with a can of
spray lube.

Not everyone is so anal about the precise amount of oil dispensed onto
their chain, I think the numbers who are may be directly proportional to
the numbers who buy chain oilers like yours - in other words, very few.

A Scottoiler is cheap, relatively simple to fit, has no revolving parts
or electronics to go wrong and does a good job at getting a little bit
of oil on the chain and stopping the flow when the engine is switched
off. What more does anyone need?

I ride way too fast to worry about cholestorol.

 

Humph. Can't be a Real Biker if you do that.

Or too tight or too proud. Some of us are doubly disadvantaged, you
know.

 

And sensors, don't forget the sensors.

Harry needs a hearing aid.

Harry needs a BMW.
