Scottoiler

Hi,

Can any of you offer me some advice...?

My bike had a scottoiler fitted when I bought it.

With the oil output set really low the bike operates normally up to
about 5k revs, where-upon it struggles as if there is a fuel and / or
air blockage resulting in a lack of power.

I noticed that the oil dispensing cable didn't have any oil in it so I
upped the oil output to the 'prime' setting, where-upon my engine
problems worsened and the acceleration threshold was much lower before
causing problems.

Once oil was flowing back through to the chain I reduced the oil output
and it *seems* to be working better, but I didn't risk accelerating too
hard.

Could someone explain to me how the vacuum tube works? Can anyone
explain how it would cause the problems I am seeing?

 

At a guess, you've got a leak somewhere, and air is getting in through the
vacuum tube into the carb and screwing up the fuel/air mixture.

Do you have the breather tube attached to the filler hole?

 

Depending on what you've got fitted (full touring kit or just the
little RMV bottle), and what kind of bike (carburettor/fuel injection)
you've got, it works sort of like this: a tube out the top of the
"RMV" or bottle of the scottoiler is plugged into an air tube entering
your carburettor. This tube is plugged into a sealed part of the RMV
bottle, which has a diaphram of rubber between it and the oil. The
diaphram is connected to a valve down the bottom of the RMV. When the
engine turns on, it sucks the diaphram up, which opens the oil valve,
and oil falls out into the delivery tube, and off to your chain. If
you have a touring kit connected, it will siphon in more oil from the
touring resevoir.

If the diaphram is broken, and depending on the state of the RMV bottle,
you could have a gaping hole into some part of your carburettor, or
between your carb and the engine, depending on where the previous owner
fitted it. On a previous bike of mine, this happened (burst diaphram), and
while I didnt get the same problem you have, the good guys at Scottoiler
replaced the RMV bottle free of charge, despite the system being well
outside any warranty. They are also very helpful both by email and phone -
give them a call.

Heya, Mike...

Surely, yes. Not all of it will be useful, mind ;-)

What bike is it, Mike? Plus, do you know which Scottoiler it is, i.e.
"universal", "touring", etc.?

[snip probs]

The vacuum tube operates a valve in the oil reservoir when the engine is
running. The valve's spring-loaded so when the vacuum goes, the valve
shuts.

As Platy has pointed out, if you've got a leak in the system, your bike
is drawing too much air and screwing up the mixture (leaning-out).

Not only is this bad from the performance point of view but running too
lean can mean burning holes in pistons so it needs sorting!

You can check whether there's vacuum in the tube by disconnecting from
the reservoir and checking for suction by placing your finger over the
end of the pipe. No suction would indicate a leak in the pipe somewhere
toward the carb/manifold.

HTH.

Hi everyone,

Thanks for all of the advice. I disconnected the vacuum cable and took
it out for a spin last night and it's now working beautifully. How I
missed being able to accelerate!

I've been talking to a fella named Mark Celino @ Scottoiler and he's
been extremely helpful. As Brian pointed out, their level of customer
service is excellent! I'm in the process of arranging to send the unit
back to get replaced.

Wik: What was with calling me Mike constantly? :s

 

No idea, Terry.

He is a very helpful chap, as are all the folk at Scottoiler who I have
ever dealt with.
