sounds like hes read about the heimholtz airbox resonation theory behind designing a airbox that pulses bradders, though he doesn't understand it and is working under the assumption that yamaha did something other than make a box to fit the hole in the bike they designed!!!
right guys im ordering the v-force reed block, just emailed the guy asking his best price he can do, i gona have to modify the manifold has anyone got a spare one with a oil feed on it?
