Fuel tubes

[Bodd]

If you're keeping the original filter box you could route the hose to a catch tank with a filtered vent hidden within said box. May need a longer hose but that would make periodical emptying of the catch tank easier. Looking at your RD and CB blogs I would imagine you could do this quite easily and there's no risk of oil mist getting on the rear tyre.

Good plan

I was thinking of refitting the chamber breather and attaching it to that but I thought it might be spraying oil mist into the empty filter box, preferable to spraying it on the back tyre but still not good, I might just get a filter and use the proper route and connection.

The rocker box breather is simply vented to atmosphere - there's a circular clip for it at the bottom of the frame.

I don't think it is, it goes to the chamber breather connected to the bottom of the air box where clip number 1 is shown in the picture below, the drain tube number 27 goes to the bottom of the frame.

Sorry, yes, you're right.  Brain fart.

Hi again Bodd,

This is what I was looking for.... The CB750 K6 breather routing.

Cheers,

As it is a cafe racer the seat is no longer on a hinge so if I make a catch tank I will have to remove the seat periodically to check and empty the contents so maybe a longer tube might be a better option, I bought 2 metres of tube and will see what it looks like fed towards the rear of the bike like in Lobo's picture.

The simplest ideas are usually the best 👍
