Hi all.. im having real issues with the carbs on my zzr600. I have ridden my bike now practically everyday for the last 2 yrs and its never let me down once. However 6 weeks ago i went to get on it for my usual journey to work and it just didnt want to know.. Ive put new plugs in, ht leads, oil and fuel filter which got it to start just once.. ive since dismantled my carbs and cleaned them .. its starts everytime but wont tick over at all.. it will run if i keep the revs on but eventually dies off.. im at the end of what i can do.. does anyone have the magic formular for my problem. Steve
