Yamaha Super Jet Billet Reinforcement Stroker Case Plate

The stock crankcase is weakened when it is machined for the billet cylinder and the stroker crankshaft. The Dasa Billet Stroker Crankcase Plate is designed to restore strength back to the crankcase while also protecting the epoxy. The Stroker Crankcase Plate is a must have for anyone running a 8mm stroker crankshaft or larger.
