| Hi again,i vaguely remember the factory gianed 1 or 2 bhp,by raising the fuel tank of the frame by about 1".The airbox on these bikes isn't a pressurised unit like the 916,as it dosn't seal to the bottom of the tank. You will achieve a ram effect using the X shaped carbon intake,but the airbox isn't a sealed resonance chamber,hence the redesign on the latter 916/955 racers. imho. Steve |
