this is true, I had a 87 suzuki lt250 r quadracer and when it ran out of gas, it started screaming, even with the key off. Had to dump the clutch with brake on to stop it

Not directed towards you, but others that see your post. Carb vs EFI. Carbs have a fuel bowl that an unloaded hot engine (no belt on) will pull from EVEN WITH THE SWITCH OFF. Amazing how long a 1000cc 2-smoke will scream at 8000+ rpm with the switch off and the fuel shut off. With EFI, you have an electric fuel pump that provides fuel, turn the switch off, no fuel. That is how a diesel shuts down, no fuel. A run-away 2 stroke is basically dieseling. Hot pipes aid in pulling the fuel. About the only thing you can do is pull the choke so the fuel mixture is not so lean.

Look guys, you're exaggerating this way out from my original post.(That's post # 7 for those of you just tuning in)

I originally said in order to diagnose the vibration problem, remove the primary and GENTLY run the engine.

I NEVER said to run it for a friggin' 10+ minutes, (or apparently longer to some of you) to where the engine got even remotely warm, let alone HOT.

You start the engine, it either vibrates or it doesn't with out the clutch, simple as that.

That's 30 seconds of run time, period.

At the rate you guys are runnin' next you'll accuse my testing / diagnostic technique as the sole source of global warming......................................................

Yeah, go ahead and google global warming and all the possible contributing factors..................
