Title: engine breather tube routing
Post by: davidrsmith on September 29, 2016, 08:42:09 PM: Hi

I am now putting my CB550k3 back together and I have the air manifold connected to the carbs and the air filter holder connected to that, I then went to connect the engine breather tube (it was disconnected when I got the bike).
Does it fit onto the bottom of the air manifold box or the bottom of the air filter holder?
Also I appear to be missing a tube of some kind that fits to the connector that the engine breather doesn't.

I would appreciate some close up photos if that is possible, the workshop manual isn't very clear.

Many thanks
Dave

Caused me to have back pressure problems and oil leaks all over when the the oil got hot end under pressure. Disconnected the tube again from the the bottom of the airbox and the leaking stopped.
