CB750 vs K1 carb inlet rubbers ... what's the difference ???
« on: March 10, 2016, 03:55:14 AM »
Softened a load of carb rubbers from CB750 K0 and K1 .. How do I tell the difference as they have somehow got mixed up  :-[ and I know there's some sort of difference.

Cheers ... Ash

The KO head spigots are shorter than the K1 spigots. I haven't actually seen a KO inlet rubber but I'd bet the spigot side is shallower than the K1 rubbers.

I believe the K0 ones are "thinner" and smaller.
