Blown XB9R

[Buelliganxb9]

OK, blew up the XB9R today, rod bearing is shot, cylinder has light scratches and needs boring or replaced. Can anyone tell me if they have put in a 1050 kit and how they like it? Do you need any head work, etc?

the 1050 kit is a direct swap, for the larger hop-up kits they want you to re-machine the head. most dont because the added compression makes some nice power gains.
