    Thank you for your answer. I've found a lot of useful things, but the dimensions intake and exhaust were not there, unfortunately. It's part of my thesis and I need still diameters, lengths and volumes of individual parts of the intake and exhaust pipes. Do you know where I could find it? Thank you

    Mike- Valve timing is in there and so is valve lift, and also dimensions for the intake and exhaust valves.

    For the exhaust system and intake system dimensions, no clue where you would find that without measuring the parts.

    Mike, you might try contacting some of the manufactures of after-market systems. They "might" be prepared to share information for you for student/research purposes.

    Best of luck.

    It is all in there, including how to recut the valve seats and how long to bob the stems on a rebuild.

    A) the port diameter of the intake is equivalent to a round port 43mm in diameter
    B) the port diameter of the exhaust is equivalent to a round port of 38mm in diameter
    C) Valve lift: intake 9.61mm exhaust 9.69mm (pp 34)
    D) valve face diameter: intake 27.6, exhaust 28.5mm
    E) vavle seat diameter: intake 23.7mm exhasust 23.9mm (pp56)
