CBR400 Idling issue.

[kurisuaki]

Hi guys,

My NC29 is having issues idle when i start it up in the morning.
It idles really weak and dies unless i use a choke. Wait at a stop light and it gradually drops till it cuts out.
When warm it idles decently, but isn't steady.

Any ideas?

Also, im hearing a clicking sound coming from below the tank. Could it be a valves issue? the bike has trouble starting when warm.

Thanks in advance!

Are your fuel tank breathers blocked??

More than likely the gauze filter in the fuel tap is partially clogged or the inline filter is; maybe both, easy fix if so.
