Is this normal for a 2 valve twin
 

I have noticed on my 900 superlight that the engine is very buzzy and a little reluctant to pull with a lot of vibration when in a high gear at about 3000 - 3500 rpm, above this it seems to clear up and pull to the redline no problem, Is this normal for this engine or have I some kind or carburation problem. The bike is all standard, though I am not sure if the pipes have been doctored in some way as it is fairly loud for standard cans?
Your help gentlemen please

Sounds pretty normal to me Ian.
 

Nice and smooth 3-3.5k around town, jerky as h3ll 3.5-4k pulling away. Just remember to keep it out of that zone, or change the gearing (rear sprocket)!

:ninja:

LOL - u have a U2U Ian - the 39T sproket is yours mate....enjoy.

ps - mine actually stutters ariound the same area, thats partly while I changed sprokets and am fitting a dynojet kit when I get around to it.
