Bike falls on it's face at 10,000 rpm and above

So I got my 08 fired after it's current re-birth. It ran well when I got it. It was stock with a k&n air filter and a muzzy slip on. Now it has the clean air mod done, k&n and full evo akrapovic system. I havn't installed my pc3 yet as I'm still debating between the 3 and 5. I know it will be running lean with the exhaust on but I didn't think it would fall flat on it's face at 10k. It not bad up until you get the rpms up there.

Any thoughts?

Thanks!

Just asking for thoughts, I was assuming that with a pc and the right map/tune it will correct this, just surpriced at how bad it is in the upper rpms. It literally hits a wall and won't increase speed once it hits those upper rpms

I seen a few theads on here with the same title before.. I'm sure the tune would fix this and if I remember they call this a dead spot. I'd try to type your title or part of it in the search on here or google and I'm sure you will find more info. Ill see if I can find them also.

Check here once
Powerband hole???

Its probably because your really lean, your running a stock ecu w/ a full exhaust and air filter? Your getting air in and out of your motor more efficiently but are not adding any additional fuel.

Get it tuned and your problem will be solved

Martydmb, that was an issue w/ some 09-12 bikes I believe, I haven't heard of any issues like that w/ the 07-08 bikes (my 07 doesn't even move until above 10,000 lol)

Thanks again!

Start with the simple stuff, fuel and spark. Go from there.

alright got the pc3 on with the right map and did some more troubleshooting. i'm getting error 62 on the bike and the previous owner had removed the upper butterflies. The bike idles fine but when you get to around 8,000 rpm it just falls on it's face. I had the throttle bodies and cables off to replace the cables. Any help to trouble shoot the error would be much appreciated.

Thanks

Warm it up and rev it in neutral for just a second and see if it easily goes near redline. If it does in neutral but not in gear under load, your fuel pump is probably going.

Check the fuel lines to the secondary injectors. They kick in at 8k. If the line is bent it will get sluggish from 8-14k. Check this picture out. Hope this helps a little http://zx6r.com/attachments/mechanic...0430131801.jpg

figured it out. When I put the new wire harness in, I had the TPS and secondary butterfly position sensor swapped. I switched them back, fired it up, no more error light and she's pulling perfect now. Amazing how frustrating something so simple as that can be. Thanks everyone!
