Homemade 4 Cylinder Carburetor Synchronizer/Manometer

An extended video of my homemade manometer with detailed explanations and demonstrations of it in operation. Very inexpensive yet very accurate. I used Snapple bottles which worked fine, but any glass bottle will do. Do not use plastic bottles; they will flex and crumple. You'll notice my design links all 4 cylinders together to give you true comparison across all 4 relative to each other.

Since it's been asked: if you get air in the reservoir line simply blow/suck on one of the cylinder lines until all air bubbles are gone; just like if a bottle goes dry, etc. You can also *reduce* the vacuum on another cylinder and wait until you pull fluid back in the dry bottle assuming don't pull another bottle dry at the same time.

And for the carburetor adapters, you can make your own (see my comment in the comments section) or buy them here: http://www.z1enterprises.com/ItemDeta...

Here's a list of required materials:
4 Glass bottles
4 Rubber Stoppers
4 plastic 'tees'
20'-25' clear tubing
4 intake port adapters (specific to your bike make/model)

Tip: put the stoppers in the freezer for a while before trying to drill the holes for the tubing and it will drill much cleaner.
