Hi all,

My clubsport has developed a strange issue when idling, when up to temperature the idle occasionally drops and it wont rev cleanly then for no apparent reason it pics up again and revs fine, any idea what may be causing this? 

It's a ZZR1200 with flat slide carbs.

Any advice appreciated.

Many thanks

Frank

Hi Frank, I think float needles & seats are a good starting point. Debris and or worn parts can cause intermittent flooding of unmetered fuel. I have seen sets bench test fine and not seal consistently due to vibration on a running engine.

During the cleaning and service, float height can also be verified coupled with throttle synch to ensure a good tune.

Hope this helps,

Rich
