Oh interesting when I opened mine it had o rings maybe whoever had it before put them on them. I’ll assemble the carbs back together then. Also do you know where I could find the A/F screw o ring not the rubber one the steel o ring or metal.Again, in the Parts diagram I don't see any O-rings on the fuel main jet tube, part number 13280A. Also, on my ZX7R carbs I never saw O-Rings and never fit any.
Zx9 E1 US, jetted k&n Muzzy full titaniumSo where to start..
I have almost the same problem except. Bike revs freely, will run to redline if you slowly roll into it. But it hesitates hard on anything above half throttle.
It started when I took it out for a blast hit about 160 and took the exit went to make a return trip and had no power merging onto the freeway. At first I thought the carbs were icing because it was very chilly that day.
I have checked the plugs all are good, replace fuel filter, fuel, checked all the lines and checked all vacuum lines. Still dont have a good idea. So I am looking at carbs and fuel pump now.
She seems to be a bit harder to start than usual as well...
Thanks for the help and I will start going through all the steps in this post hopeful to find something.
