Grinding noise/feeling around 6000rpm

[OutofFaze]

Hi again guys,

I still have this problem. I thought that it had got better, but it's still there even though some days feel better than others.

One really important observation that I made today is that the grinding feeling stops completely when i pull the clutch in when I am at the "grinding rev range" which is from about 5,500rpm to about 6500rpm occasionally a bit higher, into 7000rpm.

So, this is something that I don't really get... I don't think it is something from the chain now because it's adjusted well, lubed properly and still turns when the clutch is in because the wheel is moving. Could it be out of balance carbs? I thought that would make the tickover lumpy though, but that is smooth. I also don't think it is the air intake either now because it definitely feels mechanical. I spent almost an hour on a ride today observing this.

I'm thinking about taking it back to the Yamaha dealer again and insisting that they take a good look at it (they said that I could if I feel that it gets worse, or doesn't get better), because i'm not happy about it staying like this.

Any more ideas fellow Fazers?
