Guest Posted October 5, 2009 Posted October 5, 2009 Hi all (again!),Right, have a new problem now, or rather one that's become the priority after fixing other problems! My ZZ600 has very intermittent or even no throttle response.Got home this evening, started, excellent, sounds lovely. I'd say purring like a pussy cat but it would be more akin to a tiger having his eyes rubbed! An hour later started it again (after just refitting all of the side fairing). NO throttle response! I had to keep the throttle open (half way) just to keep it running. I held it there for about 2/3 minutes then all of a sudden plenty of revs (I didn't move the throttle from it's half way position), throttle worked for another 20 seconds (between 4-8k revs) then no throttle response again (repeated this a few times).I would have thought blocked jets in the carb and am thinking of just adding some fuel additive first. I have about half tank fuel (which is less than 2 weeks old) so unlikely to be fouled.Thoughts please peeps - easiest and most obvious first please! ThanksDar Quote

I held it there for about 2/3 minutes then all of a sudden plenty of revs (I didn't move the throttle from it's half way position), kawasaki carbs have a vacum diaphram on the top of them to open the main throttle body inside it. what you describe could be any one of the following...vacum hose splitdiaphram split or leaking badlycarb sliders stuckor a very stretchy throttle cable take the tank and airbox off and check all the operating cables work (i.e. the butterfly valves open on the carbs) check the hoses (again just in case) then with throttle open (engine off!) stick your finger inside each carb and slide the throttle body up then let it drop back down.each one should be perfectly smooth with no sticky points and should make a swooshing sound when pushed up as air escapes from above the carb body. if not, it's a full carb strip and examination...

Many thanks m8. I was trying to avoid it but hey ho, overalls on! I'll let you know which one of the infamous 4 it is, lolDar Quote
