Default clutch bearing issues

hello and thanks for reding i have a jammin 28 in a jammin x1 and i keep blowing out clutch bearings mostly frnt bearing but has blown rear one . Gear mesh is correct had others look and feel it and end play is fine a little over .5 play a spec i've read in several different tuner books and mags. any other reasons why they would blow out so quickly, running a 5 min qual. and frnt bearing inner race is gone, idd not explode yet but seal is gone and bearing is starting to go. Yes these are new bearings again mesh and end play are correct if not even a little more gap then needed. Im really leaning to 3 things. 1. chassie flex while driving flex pintching out clutch and messing gear mesh. 2. bad set of bearing but all new out of wrapper from protec and reedy bearings black and green seal metal backed 3. tip of crank is slight bent and at idle is hogging out bearing while at idle ...? any suggestions may help have been racing now for 4 or 5 year bashing since "88" but have never run across this issue any help would help thanks
