    The engine is not in pieces at the moment and i'm trying to get it started for the summer season so i'm not able to give you the timing. So i'll be back a little later with the actual port timing. The power i was looking for was a really strong runner in the mid rpm with a reasonable bottom end(all I can get without destroying the streetability). Is the max rpm target 9000 rpm too high? It would give 18,6 m/sek piston speed which should not be too high? Is the target set too high to get a reasonable bottom end? Should I cut the head in tree pieces as well to ease the possibility to mod it? Do you need the measures for the pipe and the size of the carbs as well?
