CB550K3 plugs

Ashdowner:
I'd like to think that the previous owner of my bike had spent hours on research and testing to identify the optimum NGK plug for each individual cylinder and that he wasn't in fact some dickhead who threw in whatever was lying around in his workshop. Anyhow I've fitted the standard DR7ES and it will come as no surprise to any K3 owner to read that it has made no difference to the tickover and it still sounds like a dog giving birth.

Can someone please explain the "clear-tube method of checking float levels on the P46 carbs and tell me where to fit the aforementioned clear tube?

Hi,
    Agree with bryanj, had this discussion with the D Silver bunch, after they sent me D8Es plugs for my 400/4, maybe OK for unsupressed metal caps, but my local Honda dealer recommended D8EA plugs for use with the more modern suppressed plastic caps, that was 1985, never had any spark trouble even in the wet with them, I think the above were a set of freebies from a breakers!
