hi,got a ninja the week before last it drives grand but at low revs it seems sick,it acts very like a bike thats running low on petrol,it slurs and makes deep gurglin noise like its sucking more air than petrol.it has been serviced recently and drives as smooth in every gear once i'm on the big roads does anyone with a zxr know this experience or is it simply time for a carb clean and balance?
to be quite honest i cant see the previous owner going into that depth. i'd be more inclined to ask if the needles or jets were copper thus giving high rise to wear but even then i cant see this been the case the bike has'nt done 10k miles!! but i havint got much experience on super bikes so your point is valid in any case
