The 1.00 intake pipe measures 10 mm at the bottom and 10.5 mm at the top. I measured around the circumference to make sure the curve was not causing the difference. They are both straight at that point. Interesting.
Does anyone have an FA-115 to measure the intake manifold? I would to know if the 125 is the same size as the 115 manifold where it enters the head. They both use the same valves.
