Topic: The logic behind pods

[70CB750]

From reading this forum I understand the pods are not the best thing for CB750 carbs.

Anybody knows why?  Is it because the original filter shares the vacuum between carburetors?  Or the pod gives too much air flow for the stock jet?  Or carburetors were designed from the factory to run with air box and pod is just a pour substitute?

Explanation would be appreciated, thanks.

Lack of a bell shape that you get with the stock intake boots+airbox, velocity stacks also have this shape.  The shape cuts down on turbulence and allows a steadier more uniform amount of air into each carb.  Also cylinders 1 and 4 seem to have fluctuations due to the lack (usually) of side covers.  As gusts of wind pass by the pods it affects 1 and 4 more adversely than 2 and 3, thus altering the even flow of air to all 4 carbs.  There are more and better explanations if you search.  Charts regarding to the shape of intake boots or velocity stacks.  Tuning with pods. And the Anti-Pod thread ( a member who designed his own non stock design that utilizes stacks and a foam filter)

Thank you, I should write 100 times: I will use the search before I post another stupid question

There is a a good write up in Carb FAQs - I will drop pods as soon as I fabricate decent replacement.

But the thread on non stock airbox is a nice bonus, I am looking for that one for month plus now, thanks!

No worries, I'm not one of the people who sh*t on people for not searching.  If I weren't here to help answer questions I wouldn't keep coming back.  That being said, theres a lot more info out there than what I supplied and searching will provide that.

Logic and pods don't go together.  They just the fill emotional need to look cool.
