I have found some drawings and photos and am fairly confident it's not beyond me but to start with I need to know some crucial dimensions to scale the motor accurately to 1:6.
1) The overall height from the base of the dry sump to the top of the middle aircleaner.
2) The PCD of the mounting bolts at the front of the unit.
3) The length of the block from the mounting flange at the front to the flywheel at the rear.
If anyone has a fully dimensioned drawing that'd be a great help

CAD intrigues me and I'm considering a 3d printed version also.
Thanks.
