'08 zx6r revs stopping

I've been pretty absent on the forum, but am deciding to focus more on the bike this season. I had this issue all last season but was able to still enjoy riding even though the bike wasn't at it's maximum potential.

The revs will stop when riding much like a rev limiter. When it reaches about 10k (varies within 2-5k) it just hangs out and won't go any higher. This happens in all the gears. When in neutral it revs up just fine. Possible thoughts after a bit of research are dirty fuel components? Something to do with a faulty kick switch? I noticed my bike does not turn off when I put the kick stand down so I believe that switch is broken regardless:butbut: Any thoughts?

I've never worked on bikes past simple oil changes, and filter replacements, but want to get this bike into perfect condition. It's got around 7k miles on it, but needs some maintenance for sure. Going to get repainted later this month in fact!

Have you had that bike since new? Ever had the airbox off it? Even though a lot of people will say it's the fuel pump, I'd check if your secondary injectors are connected. Got any FI light?

You're also correct about the kickstand, check for secure connection at the kickstand to main harness connector, follow wire from the stand switch to the connector and make sure all the wires are tight with no play, check connector for corrosion and if its clicked in all the way.

I bought the bike used last spring from the 2nd owner with about 4,800 miles on it. It has about 7,600 miles on it now. The guy I bought it from admitted he had the same problem but brought it to a shop to get serviced before he sold it and they claimed it was something else and they fixed that. I saw the receipt so he wasn't fudging, but apparently they fixed the wrong thing. When I test drove the bike I didn't notice the issue. It's definitely consistent though now.

No FI lights. I'm still pretty new to bikes, but am planning to do lots of research on those items you mentioned so I can really check everything out. I want to get this bike back to perfect condition. If it is the fuel pump, is it a pretty straight forward DIY replacement?

I will have the fairings off for a while so I plan to do some maintenance then. I changed the air filter last season, but need to do plugs this year, and a few other things.

Safe to assume the plastics are all OEM?

Yea check the throttle bodies, fuel injector, heck valve clearance, spark plugs, the stick coil, piston rings among other things.

All OEM Plastics. Only mod is a fender eliminator kit.

Probably a dumb question, but still kind of a noob when it comes to the mechanics of bikes...but what am I going to be looking for in the throttle bodies, injectors, etc...?
One thing that can also cause this issue is one or more bad stick coils. The service manual will tell you how to test these with a multimeter.

Cool thanks! Since I'll definitely do new plugs I will definitely check those too!
