OK, Danny, I'm beginning to get it now... I think...
You seem to have two questions, which need to be addressed separately: The first about turning off the kill-switch ("Run Stop" switch). And the second about opening up the compression release valve and opening up the throttle. I'll attempt to address them separately. And I have little doubt that others on this forum might have different opinions...
First the kill-switch... I don't think it's a good idea to turn off the ignition while running the bike at any speed above idle. Yes, the crankcase is still having oil splashed around in it. But it's not diluting the oil in the crank case that's the problem. Even when the engine is up to temperature the fuel is not fully vaporized. Running it at speed with the ignition off will introduce droplets of raw fuel into the combustion chamber. It won't run down the cylinder wall, but it will dilute the thin film of oil at the top of the cylinder. And thus, increase cylinder, ring and piston wear. So, I don't shut off the ignition until the bike is at idle. (And, truth is, I should probably stop the engine by shutting off the fuel like I was trained to do when I was learning to fly...)
And pulling the compression release at speed, and hearing a BANG... I'm presuming that the explosion is coming out of the exhaust..?? But it doesn't matter much... Explosions are a bad thing. Fuel is supposed to burn, not explode. If you open the compression release and get an explosion, guess what? You're _still_ pumping fuel into the engine. That's a double no-no. Not only will there be unburnt fuel in the cylinder, but you'll be adding stress to other components that were most likely not designed for that sort of abuse. Unless you like spending money and time on repairing the bike, or paying someone else to do it, more than riding, it's not a behavior that I would advise..
Does that make any sense?
