This is a 1441cc engine package which uses 3mm JE pistons combined with a 2008 Hayabusa crank (2mm more stroke than the 99-07 crank).  Kit includes a 3mm bored cylinder ready for exchange.  You can also purchase the 2008 cylinder which is redesigned with better windage to free up more horsepower, as an option. 

The 2008 Hayabusa cylinder option is an extra $699.95 and is sold outright with No Core required. 

 

Kit comes with a bored cylinder (core required), 3mm JE pistons, the 2008 Hayabusa crank, and the spacer plate . 

We need your cylinder as a core.
