That's bad advice Bikeguy Joe. Using a clutch to induce sudden stoppage is bad not only for the clutch with increased wear, it is not good good for the engine. You may do this regularly with normal motorcycles but the HT engine is notorious for its poor clutch and difficulty in finding replacement clutch pucks.
You dropped the ball on this response.
OP, if you can't use your kill switch, kill your engine with the choke.
