What a Shame..!!
PatM:
I agree with the speed scenario- mine got considerably more mileage that yours and its been stripped many time- it like lots of revs and whips up to 70 quite easily- but that's enough for a 35-year old girl- I don't want something falling off or dropping. Off for MOT tomorrow as done enough fettling and need to ride it legally :-) Ive a few newer bikes to ride that will take more of a thrashing.
400/4s do like revs and mines ok on tick-over, a slight hesitation below 3k and bloody marvellous over that - I don't take it over 7.5k
Very amusing reading the re-build- nothing ever goes smoothly , especially carbs and fuel.

You are right there...!!!
Got all the bits from Silvers - after another trip to FEDex building cos i wasn't in for delivery pain in the ass - and fitted everything within 30 mins. Zoomed off out for a ride but its still not right. Its not bad but I remember the 400's Ive ridden in the past being super smooth with perfect carburation if they had original airbox. This has a noticeable glitch on initial pick up. I wasn't happy with it so carbs are off again. There is definately still a problem somewhere most likely in the primary circuit.
Everything else is done, I filled it up with fuel last night and came out from paying to a little gathering that had formed around it. Had a 10 minute laugh and a joke about the old days with some guys that obviously remembered their 400's very fondly. I never actually owned a 400 four I was always a 2-stroke nut (still am).
So the carbs are on my bench AGAIN. Initially they were very bad and as such I went over and over them but I must of missed something. Doh. All good fun eh. What else would I be doing - "couch potatoeing".
PatM:
Well, mine passed its MOT but I have to admit- my one ALSO has a slight hesitation picking up- its ok after 2.5k- so ill be interested to read if you nail the problem.
Ive another set of carbs I used a month ago- stripped, completely re-jetted using kits- the only thing I didn't do was separate them- so I still have some O rings left over. The bike DIDNT like them- far worse hesitation and an annoying tick-over drift like they were leaning out- would drift on tickover up to 2k, then settle after a blip. I have a balance between the set that's on there which are a bitch to start from cold- and the other set with the poor running.
Hey Ho- keeps us off the streets but in the wifes bad books with the smell of petrol in the air over the house of a weekend!

Well in both our cases there is a blocked hole somewhere. This one doesn't settle to Idle correctly either. It revs high for a while sometimes before plummeting to stall. I know what this is and have fixed it loads of times in the past but I cant remember at the moment. Hahaha. I'll think of it later. Its basically lean on the primary circuit. must check how the fuel is supplied via that circuit, (wether its a small hole in the bottom of the venturi etc). I did rely on my airline cleaning these passages (maybe it didn't).
PatM:
Yep. did the same and plenty of carb-cleaner- some ended up in my face due to the over-exuberant use of the air-line. Carbs are great when they are working but not so great when they are 35 years old.
