Default Helicopter drifting aft and left

I have a T-rex 600 Nitro with a Tracx head and Vbar 5.2. The heli is stable as a rock in hover for the first few minutes. Throughout the flight the rotordisc is starting to drift more and more aft and left. The tail does not drift at all. Can this be due to vibrations? I have recently changed the bearings on the engine and the dampeners on the head (Kbdd green). Any suggetions what to do? I have attached the log, which shows pretty good vibration level, might that be due to the new stiff dampeners?

So what's the vib levels running.
To many vibe warnings there. I use 2 layers of 3m 4010, steel plate and then 3 layers of 4010 and then a strap with the same tape bwteen the strap and sensor. It cut the vibe levels in half from what I had before. It's almost like gyro gell built up like that.
Remove the blades and run on the bench, watch for the swash staying level while ramping the motor rpms

Not quite sure, it`s a really thin gyro tape, 1 mm thick, maybe a little thicker. Had a thicker on before (about 3-4 mm) but it didn`t like that at all.
