Quote from: taysidedragon on October 25, 2018, 03:24:57 PMJulie, that's a good theory, but the engine breather hose goes over the top of the carbs, in the frame clip under the frame tube alongside the wiring harness, down behind the plastic air box and joins the contraption under the air filter. 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?

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. 🔧👍
So are you saying that they have both numbers on and you just turn them round to show the correct number? eg 1 and 4 are on both sides of the outer insulator
Couple of things.Julie your insulator picture on post 11 clearly shows that the insulator from number 2 cylinder is fitted to number 1 cylinder, sorry I just notice stuff like that.
Oh no! I'm surprised that you could get the air box on. 😟

I'm surprised that you could get the air box on. 😟Everything fits perfectly, or i made everything fit perfectly with no problems at all . I have done over 1500 miles on her since rebuilding the engine earlier this year and she's running just fine, other than a bit of dirt in an idle jet (also on the fettle list) i wasn't planning to do much else to her this winter, now i'm going to be swapping parts around to their rightful places
I suspect Julie that the insulators are handed slightly, in that the outside/inside ones may bend very slightly inward, hence why different part numbers and why they are numbered. You may not have noticed any problems getting them engaged with the carbs as they are such a bitch to fit anyway or maybe you did notice but just thought it was normal. Got to say I'd forgotten about the numbers on them, only really a problem if you remove them for head work etc. Of course Trig will say he knew Julie, he's a man and men don't like to admit they didn't know something even if he really didn't know. What we need now is someone who has a 400 head off and will fit the insulators incorrectly and then correctly and post pics of them in both cases so we can see if there is an alignment issue.
