Hello!
I´m a swedish happy owner of a cbr 900-98. The bike was running smooth and without vibrations, untill one day when it suddenly started to sound a little darker, and i could feel these vibrations coming from the engine up through the tank.
They have recently checked the bike and the engine, but the honda shop couldn´t find the fault, they checked the clutch, and other vital parts of the engine.
The overall condition of the bike is in "mint condition", and the bike has been carefully driven.
So i wonder if anyone have experienced something like this.
There is no abnormal engine noise, other than i heard a slight change in the exhaust sound.

Thanks in advance; Pete.
