October 22 2007 - Does the Hayabusa engine need any upgrading? The hayabusa engine is a solid little engine, and if treated right will give good service in totally standard form. Mine is totally standard apart from the dry sump system. Pistons and con-rods only need to be addressed if you start to upgrade the engine above 200bhp, especially 'violently' with turbo. At the start of the project i thought i may go down this route, but plenty of horror stories later, and potential need to comply with racing formulae, and turbos are not a good option. I was lucky to get an engine from a 900 mile 2006 bike, and i'd recommend similar - brand new is typically very expensive, I've heard £6000, so second hand is a good option - i paid £3200 including dry sump. |
