I personally wouldnt fit an air filter Jeff , unless you have several hundred dollars to get it dynotuned to run with one fitted. Its been like that for 5 years and is fine without. With one fitted it will be a gutless peice of shit, but you seem to be turning a good bike into that anyway from what im told. The offer was there to ring me and i would tell you all you had to know but you know best.
Dont ring ok - offer withdrawn.

i was going to ring you when i had time. i was told by dave freeman that it was bogging because it didnt have an air filter on it which is why i put this thread on here

And the reason you approached him to start with was ....... ?
Same as the rear sprocket, you got a blank for it and have to rework it but i told you i will tell you even the part number if you rang.
The reason its bogging is you are running the wrong fuel , again i offered to inform you but you didnt bother.
People are trying to assist you and you just dont want to be assisted.
I am at a loss young man.

sorry to butt in there guys but i also have an 89 CBR400 that is bogging down horribly, when i bought the bike none of the vacuum pipes or filter was connected and i was advised to re-connect it all up, but no change,

any suggestions would be very much appreciated

cheers

clean the carbs and if you race it keep the revs up higher

thanks mate, one of the first things i tried tho, i've also changed the fuel filter, plugs and leads.

i don't race it at the mo but was thinking of using it as a track bike

also check the chock is fully off

[kwakalover]

yeah, that was one of the things i first checked too, but thats what it feels like - that the choke is permanantly on

Try Econohonda first (07 884 8810). They'll be cheaper and quicker.

CBR400's...once tuned a bit they don't work until at least 10K RPM. Not a beginners bike but very rewarding. Stock it should pull OK in the first 3 gears from idle but you've got to have the carb balance and tappet adjustment pretty well spot on. Not really an issue on a racebike. Could possibly loan you a CDI unit to test.

Check plugs, compression test then dyno would be my next suggestion.
