@@jimrawnsley still just in my head but modified by what I learnt there. A simple Stevenson formula could be done, but I am terrible in wanting to do more complicated stuff. I have so many complicated projects waiting to be finished!
Very challenging squeezing a tall driver into a mid-engine kart, you have created a close replica of the torsion bar system and used it to advantage in providing maximum leg room, a clever solution indeed. On my kart my feet will be in front of the tires, wedged between A- arms and shock absorbers.
Jim, can you share your overall frame measurements? I'm getting started and thinking about the seat position as the auto union design has the seat way forward. cheers.
The frame is in two parts. The overall dimensions in width of both frames give or take a mm is 510mm. The overall length of the front frame is 1320mm and that has a length for driver between rails of 1220mm as the rails are set in a bit. The rear frame (Visible, it has legs inside the front frame) is 840mm. This comprises of a space between rails in length for the engine of 385mm (I can move the engine 55mm backwards and forwards in this space to tension chain) and a space for the axle gear between rails of 310mm. The front track is 965mm centre to centre. the rear track is yet to be set, but can be up to 1m. Wheelbase is 1800mm
Remember, this is a caricature of the original, I have to steal space for the driver fore and aft to get in it. Provided the visual cues are there, it will be close enough for a cyclekart.
