Yamaha XSR700 MT-07- Ported And Polished Modified Cylinder Head MiniTwin Race
This was taken off a race bike. Cylinder head porting refers to the process of modifying the intake and exhaust ports to improve their air flow and if you are building a superbike-spec engine then a good cylinder head is the place to start. The ports have been contoured, re-shaped and polished for good flow across the valve lift and rpm spectrum. I was informed that the head came from a MiniTwin / Twins Cup “Superbike” (some people call them FZ-07R or MTR-07) so an actual race bike!
