KTM Sportmotorcycle — Engine noise and vibrations.

Bike engine coolent started leaking after 2 months of bike purchase and I took it to the dealership, they replaced the engine head, couple of days after that Engine noise (ticking sounds) and vibrations started and they are still present, gave it to the dealership again, they did valve adjustment, but still the problem is there, no one knows what to do, they keep telling me to just ride the vehicle, but with all these vibrations I'm not even inclined to ride it.
