Blaster standard bore is 66mm. If your cylinders are already at 67mm or need to go more than 67mm to clean up an upgrade would be required to a piston that goes bigger such as Pro x, Wiseco or Wossner.

Boring a cylinder needs attention to detail, if it is going to be done right.  Here at Full Bore we take every precaution to make sure it is right and will custom size to what your needs are. Our strict quality control policy ensures specifications will be met. The cylinder is bored, sized, and followed by a three stage chamfer to ease the rings back in and increase engine life, and final hone for the proper cross hatch.
