wayne, i have a shop here locally. I have installed many flywheel/chutches lol. Have you ever seen the bolts that hold flywheel to the crank? its a t55 torx, not a typically 14mm or 17mm head bold. There is no washer and the head on the t55 is so small , that the contact patch that it hits on the aluminum. After time and time again of burnout/ holeshots the aluminum get fatigued. Then the flywheel can move in the bolt holes, eventually causing the bolts to shear off in the crank. Its pretty hard to install the flywheel incorrectly hahahaha. I replaced the bolts with factory one , applied red loctite torqued to factory specs and it still came apart. time for O.S. Giken...
