Q. Do I get everything in the kit to balance
Yes. The Carbtune II comes complete with full instructions
and warranty, rubber hoses, dampers and both sets of adapters, 5mm
and 6mm, to fit virtually any bike.
Q. How much does it cost to get it delivered
to me in the USA?
A. All the prices are on the prices page.
Postage is free to the UK, £1 airmail to Europe and £3
airmail to USA and Rest of World. Or just click on what you want
in the shopping cart and it will calculate the price.
Q. My bike has fuel injection. Do I have
to balance them?
Yes. You have to sync the throttle bodies in just the same way as
you do with carburettors.
Q. I have a 5 cylinder bike. How do I balance
Ok Valentino, we don't make a 5-col Carbtune so I suggest you change
to a 4-cyl bike.
Q. What sort of liquid does it use?
A. It doesn't use any liquids. It has columns of stainless steel
that float through guides to indicate the vacuum.
Q. Is it as accurate as dial or clock type
A. Yes. Infact it is more accurate than any dial or clock type gauges
that we have tested. It has better resolution than typical dial
gauges and is also much easier to read. The four columns are right
beside each other for easy comparison unlike the pointers in dial
Q. My dial gauge pointers flicker up and down.
Is the Carbtune II better damped?
A. Yes. The moving part in the Carbtune II is a solid rod. This
is too heavy to flicker wildly up and down. It does flicker a bit
without any damping but with the damping supplied with the Carbtune
II the fluctuations are very small. In fact the Carbtune II needs
a little fluctuation to work properly. We can supply stronger dampers
Q. My dial gauges always need recalibrating,
is this necessary on the Carbtune II?
A. No. The components of the Carbtune II are matched during assembly
at the factory and will not need any recalibrating. They work on
a different principle to dial gauges.
Q. Can I get spare parts if I lose or break
A. Yes. All the loose parts are available from Morgan.
Q. What happens if the Carbtune gets dirty
or greasy inside?
A. The Carbtune can be dismantled for cleaning and this is described
in the instructions. It is very simple to do.
Q. Is the Carbtune guaranteed?
A. Yes. It's guaranteed for a year but we expect it to have a very
long service life. Some of our original Carbtunes are still in service
after 20 years.
Q. Why is the 2-cylinder model almost the same
price as the 4-cylinder model?
A. Both models use the same casing, connector blocks, and mouldings.
They also take almost the same time to assemble and test so the
production costs are not very different.
Q. If I buy the 2-cylinder model can it be
upgraded to a 4 in the future?
A. It's not really feasible as it would have to be completely disassembled
and then rebuilt with matching components.
Q. Does the Carbtune II work on cars?
A. It does work on some cars, mainly high performance cars, but
most cars don't have any facilities to connect gauges to them. It
works on BMW M3s, Lotus, Alfa Romeo, Aston Martin, Ferrari and similar.
Ring for details.
Q. Does it work with outboard motors?
A. It works with the new generation of 4-stroke 4-cylinder engines.
Q. Does it work with snowmobiles?
A. It works with the new generation of 4-stroke snowmobiles like
Q. Does the Carbtune work with 2-strokes?
It will work on any engine as long as it has these two points:
1) Somewhere to connect it. The connection will either be a blanked
off screw hole or a stub for pushing on a rubber hose. The Carbtune
comes with both 5mm and 6mm adapters for screw in fittings and a
5mm id hose for the push on fitting. If you engine has these fittings
it should fit. Most two-strokes do not have any connection points
although Suzuki triples do.
2) The readings are between 0cmHg to 40cmHG. No problem with 2-strokes.
