Did you check the rubber hose was connected on the bottom of the sensor too?

I would also listen for the exhaust valve at key on. Ive seen where the valve is stuck and not moving, causing something very similar to your issue but around 6k. It should cycle full open, then return to closed position. Generally this will throw a code though, are you seeing a check engine light?

The bike hits 8500 revs and refuses to rev higher. It does sound like a bike hitting the rev limiter.

I ran the bike with the tank propped up slightly to ensure there was no kink in the fuel hose. It has a full system so there is no exhaust valve and it has maps to match. The map sensor is there. The tilt sensor is all good. The clutch switch works as it must be used to fire the bike up.

Any other ideas please?

Check spark plugs? My ex girlfriends car got to much oil put into it from a dealer one time and after refused to rev past 3.5k since it was dumping oil into the cyclinders, then ****ed her spark plugs of course. I am guessing it was the ECU keeping it from going any higher, but really not to sure. Just throwing a suggestion out there.

Open the airbox check for debris. Check oil level.

Thanks. If you read my first post you will see that I have eliminated several possible causes and many helpful things people are now suggesting are already covered off. I do appreciate the assistance people are trying to provide but could you read the initial post to get the full picture and then share any new ideas. It's a knarly problem for sure.

Sorry. So you say you see the intake flap opening. Make sure it's still open at 8,000. Also when you had the tank off did you check to make sure the throttle bodies were opening fully at full throttle?

Thanks for this check. I'll have a look tomorrow as it's a little late for an open pipe at 8K. It may cause a few heart issues for me neighbours.

TPS reset ?

Wasn't there some kind of launch control system recently implemented in TuneBoy, which would explain the consistent revving ?

TuneECU is your friend. Search the forum for the scoop. Another option (if you have an Android phone or tablet) is Torque OBD. It's pretty slick.
