The frame will accomodate a 4 in-line, 600cc Yamaha unit engine (I will have to replace the airbox with some filter cones to avoid interference with the backbone, but that shouldn't be a problem...

The wheels are stolen from a Kawasazi ZX 12-R (200/50 rear tyre).
The girder's shock is a rear shock from an Honda Rebel 250.
General dimensions (in millimeters, I've already converted them below for you imperial guys and for blonde, sweet girls off course...

Rake: 40°
Trail: 77.88mm [3.06"]
Neck Height (measured from the right end of the lower cup, as in Gary's drawing): 642.03mm [25.27"]
Ground clearence: 108.64mm [4.27"]
Front axle height: 300mm [11.81"]
Rear axle height: 315mm [12.40"]
Wheel base: 1796.94 [70.74"]
Girder length: 750mm [29.52"]
Girder links length from center to center: 110mm [4.3"]
Some girder's shots:
As you can see the girder is a little bit on the stubby side, but I had to make it much shorter (8.5") compared to Gary's one to get an acceptable positive trail, while maintaining the links at a reasonable angle with the ground (between 10°-12°).
I've checked for interferences and I shouldn't have problems; the rest of the measurment are all in the recommended ranges, I suppose.
My only question is about the lower shock mounts position: is it ok to have them pointing up as you can see in the last two pictures, or do they need to be at right angle with the girder's front (straight) leg?
Many thanks and feel free to let me know if you see something that seems wrong in the whole assembly..
