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
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)!
