1977/78 cb750F Rubber Intake Manifolds
« on: February 13, 2024, 11:58:46 AM »
Digging out what I need for the cb750K6 and came across these (in front). All four stamped with a number: 410 and numbered individually 1,2,3,4. They are definitely a set. May have come with my Carlini cb750 Chopper that had a different set of carbs. Anyone know what they are?

410 means 77/78 cb750f2/3.  If those are in good, soft, flexible shape, someone definitely needs them.  Might fit k's too?...I think the f's had bigger outside diameter spigots
If it works good, it looks good...

The numbers refer to the cylinder that they go onto.  That way the installation angle is correct.

Gentlemen….. Thanks for all the info. I think these might work on my Rickman CR so I’m going to put them away!
