Maybe time for a carb balance? Was the air filter changed recently for another standard or a K&N? Is the idle at all lumpy?Andy
Another thing to check is the your throttle grip and make sure its still glued in place. This happened to me and the bike wouldn't go above 7k rpm as the grip was slipping back....took it off glued it back and sorted
Clutch slippage is quite obvious as it results in a rise in engine revs without any increase in speed, it's most likely at peak torque i.e. 8500 rpm with the throttle fully open. Doesn't sound as if that will be your problem if the only thing you notice is a speed limiter effect.If the air intake is clear and the fuel supply isn't restricted (kinked fuel or tank breather hoses) then maybe it's the sparks... a TPS check might be worthwhile.

Although it would also be doing it in the other gears if that was the case?
And for you all to laugh at heres me being a complete moron six months ago when I put the new down pipes on ... [/size][size=78%][/font].. yeah there the wrong way round ... Cheers guys - see you at the NEC !!
Hello all fellow foccers,apologies for a latish reply, currently at work so it will be a quick reply. New pipes have had no effect previously and have been on for over 6 months, the bike revs perfectly fine to top end in all other gears under hard / gradual acceleration. In sixth gear however when reaching the 110 / 115mph region i can feel a vibrating coming from the rear of the bike, which is rather alarming, I wonder if the sprockets need replacing asap. They are not shark toothing or anything to give any immediate signs of damage (and yes the front sprocket is fine with the new 12mm nut) I'll take some piccy's when I'm home tonight hopefully. Foc sake
