About your kickstand. I've spent considerable time hashing though how I'm going to approach this probelm when I get started putting mine together. Let me see if I can explain this without confusing eveyone! Sorry, I tend to get a bit wordy!
Have you considered an under the dash foot operated parking brake lever to activate a pair of outrigger side stands by cables? With one kickstand outrigger on each side you wouldn't have to worry about being able to get your leg outside the body work as much. Those doors are going to be tricky, especially with the hatch type entry door. Those parking brake levers ratchet on the downward stroke and are released by raising the latching cogs with either a solenoid or manual release levers.
With some small limited swivel style jockey wheels on the kickstands tips you could apply as much pressure as needed to keep the bike upright. The wheels will give you enough rollout from a stop to aquire your balance from a dead stop befire stowing. Add some solenoid to release the brake lever rachet and you can stow them quickly with nothing more than simple springs and a push on a button or yanl on a small lever.
I've thrown this idea out before, but I can't find where I've mentioned it here in thei thread. I went back 8 pages!
My design for my bike will have two pedals side by side so I can innitiate both together. (I've got big feet!) Then if I find myself on a lean it will just be a simple matter of pushing the low side to get back to center. Then with individual release buttons when at a stop light I can use my foot to hold pressure on the high side pedal and let some down pressure off the high side gradually. Maybe add some manual release levers to allow fine tuning the down pressure without tripping the solinoids.
I would think that if the E brake pedals were on the left side mounted above a foot shifter and you used a hand clutch they wouldn't add too much activity to the left foot. A push button mounted on the steering stem would make stowing the parking stands a simple matter once underway.
But, then again if you added a Vespa/ Lambretta style clutch /left hand grip rotation shifter, your left foot could concentrate on balancing on the outriggers when stopped.
It makes perfect sense to me without adding all those potential leaking hose fittings and slow reaction times with pneumatics. Parking brake cables and housings are plentiful in salvage yards and almost free. Not much demand for them.
Just thought I'd throw that out for consideration.
I hope it makes sense!!!!!
