question-spec clutch install on 165

ok has anyone ever installed a spec clutch on a 165.. it came with a piolit bearing and i was wondering if it was used in the install.. i'm having probs.. put the bearing in and it seems to be holding the tranny up from going all the way through the fly wheel and into the oppening.. it seems to be hitting the bearing, and pinching it ( the shaft/spline ) and not letting the motor spin freely.. i'm stumped as wether i'm to use it or not..

Thanks

The pilot bearing is not needed, I have a Spec Carbon-Kevlar and it works great so far.

yeah dude thanks i got it figured out.. just wanted to make sure tho.. didn't want to do it wrong and find out later...
