So I went for a ride and was really impressed with the bike behavior with 2 exceptions :
- instruments in the faring were dancing furiously all the time,
- guttural vibration was slightly felt with speed 60 - 80 km/h but became really intrusive to the point of a strong feel even in the handlebar around 100 - 120 km/h
Bike was dropped in the past, tank was painted and faring has a slight crack in the left side touching tank.
My question is - could this kind of vibration be caused by lets say any imbalance in throttles, dirty injectors or faulty ignition set up, or something got really screwed during motorcycle drop. I suspected one of the crank bearings going out, but oil pressure lamp showed on turned of engine and never came back during a ride.
