Grinding noise/feeling around 6000rpm

[OutofFaze]

Hi guys,


I'll certainly check the air filter element. Had a look in the manual and it looks very easy to check. I will also remove it completely and reassemble the tank and seat, then run it 1km down the road and back to see if the 6K thing changes (it will be different with more flow if my air/acoustic theory has any truth in it)... then i'll put the filter back in before I cane the engine completely. I was thinking of getting a K&N filter for the bike, but does anyone know if that makes it TOO lean then?


Also, like Limax and Razerider said, it could also just be the "rough" zone... and if my carbs are a little out of balance then it could *enhance* the feature

Anyway, i'm glad that nothing serious seems to be wrong and at least it prompted me to really go over the bike so i have a good idea of the state of everything now, other than just the shiny and newly polished looks!


**by the way... there is a high possibility that all my worrying is a result of becoming too attached to a newly purchased bike I called it "Francesca" FFS because of FZS 600... lame right?!**
