demographic:
I've just signed up so I could view that Patent properly and I'm not dead impressed with its design, you would need a long plug by the looks of it, also you would have to drill the plug threaded area.

The thread is 10mm x 1.0 on the saw valves.
From the looks of the plug type he is more than likely counter boreing the spark plug seat and then drilling a hole along side of the plug bosses threads and then routing the gas to the valve in a similar way that I have done with the remote valves. The plug is probably the same size as stock.

I don't suppose you have seen one with the little blue knob removed? My KMX125 from many years ago had a handlebar mounted choke that was rather handy as I remember it and I wonder if it would fit.
KawPatty:
Do you have to reset the valve if the bike fires but does not start or will it stat set?

You do have to reset the valve if the engine fires and doesn't start. That is a small inconveniance. The remotely opperated valve solves that problem.
I am currently working on a completely automatic decompression valve. All you would have to do is kick the bike like a KX450f.
