Twin Power’s 4.25-inch Milwaukee-Eight Big Bore Cylinders are factory fitted for the popular Wiseco Black Edition pistons. When combined with Twin Power gaskets, a 107 c.i. engine can be converted to 124 c.i., and a 114 c.i. to 128. This is strictly a bolt-on kit, as the special gaskets eliminate the need to weld or otherwise modify oil or water passages. The cylinders are offered in a factory style black textured powder coat finish with highlighted fins. $449.95.
