velocity stack help!
« on: July 30, 2013, 01:51:52 PM »
I want to put screened velocity stacks on my '78 cb750K w/PD carbs. The OD of the intake side is 46.75mm. I have scoured and scoured the internet and forums, but cant seem to find any (Im looking for the standard aluminum ones, not a $200+ billet set).

Surely someone makes these...any help please?

I ordered a set from them a week ago, should be here soon.  Went with them per recommendations from other members.

No such thing as standard aluminum stacks for stock Honda carbs ...
