What is the BEST way to syncronize Banshee carbs accurately?

 

I have never owned a vehicle with multiple carbs, but everytime I look in my JC Whitney catalog, I see a carb syncronizer. It says works with all multiple carb setups, so I don't see why it wouldn't work. Other than that I have no idea.

Some banshee owner will be able to tell you an easier way.

 

It is very simple. No extra tools are necessary!

If they are the stock carbs:

There are small sighting glass holes on the right side of both stock carbs, just below the top cap. Use a wet Q-tip to clean these glass sights if necessary. Have somebody SLOWLY push the throttle lever.

At the same time, look in these small sighting holes and you will see a round, metal colored mark appear that will eventually come up and consume the entire sighting glass area.

These round marks should be even on both carbs.

Adjust the top of the carb cables to compensate if one of the carb's slides moves before the other, moves higher/lower, etc.

If you have aftermarket carbs:

Remove the air cleaner and/or rubber intake boot on the rear of the carbs.

Have somebody SLOWLY push the throttle lever.

At the same time, look into the carb air intake (rear of the carbs). The slides inside the carbs should lower and raise at exactly the same time, position and level.

Adjust the top of the carb cables to compensate if one of the carb's slides moves before the other, moves higher/lower, etc.

 

It was mentioned above to use a synchronization gauge from JcWhittney.

A guage is fine...Just do not use a mercury type. A 2 stroke will bounce the mercury all over the place giving you an inaccurate reading.
- Plus the banshee does not have the fittings installed for a vacuum gauge.


The most accurate gauge I use is a Suction vacuum gauge.... But you still have to remove the boots from the airbox to use it.
I would go with the explaination above....It will get you close enough to run good.
