after having my 53 plate ZX9R for 18months i,ve found that the gear box is starting to feel clunky and noticed that if the bike is stood for a couple of days the green neutral green neutral light is not on when the ignition on even though the bike is in neutral. I,ve checked the chain tension and adjusted the clutch but its still the same or maybe this is just a characteristic of all 12000 mile ZX9Rs

**ZX 9 R CLUNKY BOX? **
No I dont think it is a characteristic of your bike.The early models ie C+E models did have gearbox problems.With yours it may just need a oil change and new filter.And also maybe the gear change pedal and tie rod and change lever boss adjusting to suit you or just adjusting to work better.Also you say you have adjusted the chain but have you checked for wear?. Also you say you have adjusted the clutch but did you take the cable off and check it was free moving and lube it?. As for the neutral light not coming on all the time I should think this to be a bad connection at the bullet connector on the end of the neutral light switch or chain lube build up pushing the conector off.Or a faulty neutral light switch.Could also be a loose or bad connection at the bulb in the clock? but it is usually at the switch.The switch is under the drive sprocket case so check also drive sprocket condition and retaining nut is tight while your in there.
