Hello. What is the angle, bend in degrees on the header on the far right ? Also, could you post a picture of the middle header, the top part as if you were looking in. Lastly, are the measurements on the header in the left of the picture typical for this style (the part that wraps around the engine , is it 70mm from inside edge to outside edge. ? Thanks, this would not be for a typical installation,ie, zenoah, etc.
