Before I start I just wanted to say thanks in advance.
My 04 R1 seems to loose power when on 6th gear. I'm on 9500RPM 132klixx. I thought it's was the spark plugs at first. Changed it and same problem. Put some injectors and fuel lines cleaner still same. I did some research on R1 forum and so many possibly things that may cause the problem. E.G. injectors, exup, clutch, tranny, tps, one suggested to put power commander. So If anyone here have the same problem before, how did you fix it? Or anyone here have any idea what's wrong please help me out. Again thanks in advance.
