    The gauge set is designed specifically for motorcycles and is much more accurate and
less likely to break than "mercury stick" gauges.
 
  Inaccuracies  and chance for breakage are eliminated by using one gauge - gives the same accuracy
for all cylinders. This gauge set allows you to synch the carbs to essentially zero variance and this
makes a big difference in engine performance and power output.

Q. Why do I need this tool?

A. All engines benefit from "balanced airflow" which means that each engine cylinder gets the same amount of air, thus,
the same amount of fuel. Motorcycles use separate carbs or injector bodies which usually have "synchronisation"
adjustments to balance the airflow to the cylinders, which is a good part of the reason motorcycles make more power than
cars. Conversely, the carb adjustments, particularly balance, being off just a tiny bit can make the cycle run very poorly.

Q. Aren't "mercury sticks" more accurate?

A. I threw my last set of "sticks" in the garbage can 20 years ago because they were a faulty design. The more I used them,
the worse the cycle ran - a common complaint from riders who have Dealers "synch" their carbs is "it ran worse afterwards."
It's not that a mechanic cant read a gauge, their gauges are the problem!

Motorcycle "mercury sticks" are less accurate than dial gauges, and more prone to damage because:

1.) Sticks use mercury, mercury is a poison.

2.) Sticks use "damper valves." ONE TIME of opening a damper a little too far, and the mercury is sucked into the engine.
Whats worse than sucking ALL the mercury in, is that several times of sucking a small amount in leads to low mercury level in the
reservoir and loss of accuracy due to air bubbles in the gauge columns.

3.) The idea that 'sticks'  eliminate "parallax errors' in mechanical gauges is absolutely false. Dial gauges do not have parallax error,
that parallax is an operator error due to holding the eye in the wrong position. "Sticks' have a WORSE error in that if the stick
is TILTED to one side, the gauge goes badly out of calibration.

Q. Whats the benefit of having only one gauge?

A. With one gauge, it is impossible to have inaccuracy in the readings, because each reading used the same gauge. For about
the same cost, a larger gauge is used, which is easier to read, thus, more accurate. It is useless to have more than one gauge,
because only one carb or injector body can be adjusted at a time!

Q. How do I "synchronize" the carburetors?

A. There is no such thing as "synchronizing carburetors." To "synchronize" means to make things happen at the same time
(think - synchronized swimming). The cycles carbs need to be "balanced" which means they all flow the same amount of air.

Balance is accomplished by connecting a vacuum gauge to the intake manifold of a particular cylinder, then adjusting a screw
on the carb or injector body to adjust the amount of air through the intake manifold. The screw adjusts the opening of the throttle
plate. In an ideal world, making the throttle plate openings exactly equal cause the airflow to be balanced, but in the real world,
its not that simple. Errors in fuel flow, cylinder - ignition timing, valve leakage, compression changes etc cause airflows to be upset,
so airflow for each cylinder must be balanced by individual cylinder vacuum reading.

Q. Are carbs/injectors easy to balance?

A. NO. It's a difficult process that will make you throw tools the first time, but it is critical to do it for proper
engine performance. The increase in engine power, along with less engine heat and longer engine life is well worth the
effort needed to learn to properly adjust carb balance.

 Q. What about instructions?

A. Other sellers give you instructions on how to connect and use the gauge, but thats useless, you can figure that
out on your own
! My instructions show you how to set the gauge up, AND the PROPER procedure for balancing
the carbs or injectors.
