400 none starter

clem, funny you should say that. the noise is a very loud knocking which disappears around 2500 rpm but it does have a slappy sound to it, what annoys me is I lent my gauges to a chap about six years ago and haven't heard from him since, :(

If you got away with just cleaning flaot-bowls and a blow-out then good job. I suspect however if they were that bad that the running will be all over the place with fuel leaking/sucked up the main jet sides. You should re-jet with a DSS set or Keyster kit- costs about £90 but eliminates an obvious source of trouble..well, one of them...

;) thanks , good sound advice. it will have to wait a while mind, few bits and pieces to do yet. but they will get done.

>:( well pat, you were spot on. just gave it a run up and middle pots cold, then carb drain pipes pissed petrol all over the shop. ho ho, back to work.
PatM:
Ive got one set of carbs on the bike and 2 sets as spares= All 3 sets will exhibit one problem or another...carbs, very fickle things.. Actually, I have to say that my younger brother had at least 3 400/4s in the mid seventies and one of them used to piss fuel out carbs now and then- and it was BN..
What I found the re-jet kid did for me was to seal up the main jet- as when I brought my present one it was a non runner, only because of carbs.
Ok, Ive spent a bit tarting it up, but it would start and run initially,
