That's what I have been looking at Paul in my manual, what route does yours take?

The one above in the manual :)

Ok, I will re route mine then, I don't like being too different to everyone else 😂😂😂 But, it also F's my theory of why they have flat spots on No's 2 and 3. I don't think it can be just for ease of handling, it just doesn't make sense to me.

The routing is shown on p87 of the dealer manual. I guess this keeps the rubber hose away from the engine heat as much as possible.

Do you know something, that's bloody amazing and yes, I can see it on page 87. My old 400/4 and this one has it routed between the carbs, I will have to re route it but the angle at the bottom before it goes into the air box bit, would be so acute, I would worry it would clamp itself off.
Edit...does anyone know if the original factory fitted breather pipe had bends shaped in to it?

Julie, I thought that it would be a tight bend at the bottom as well but it's not too bad. I made the mistake of fitting the breather hose after assembling nearly everything else. Getting hands in there to fit it to the plastic gizmo is a nightmare!
I thought I would have to remove a few items to make space, but I did manage it eventually, with a few skinned knuckles. The chainguard was off which helped. 🔧👍

Luckily, I have very small hands, just right for getting in awkward places ;D ;D My 400/4 is off the road now for the winter so i will add that to the fettle list.

They are 2 types. One is marked 1 and 4, the other marked 2 and 3. It depends which side you're looking at.

Yep. Took me ages to notice it!
