new dv888 w/ konkave tilts

so i finally got my new dv888 in and its great , but i put a konkave on it and the dv888 tilts after it spins for a few seconds, like to the point where it touches the string. it does this with the stock bearing too, do i just new to break it in? or should i send it back and exchange it???

It plays perfect stock.

ill try with the stock bearing
