I already specified the free moment of kicker in Unicorn cb 160 bikes. \nissue : all of sudden the vehicle stops. Can not be started either through kicker or through Electrical starter. Kicker will move freely. No compression traced.\nSalvation: Keep the bike idle for 10minutes and allowed to cool the engine. engage the first gear and start the vehicle through kicker. after two kicks the wheel tends to rotate and after the following kicks it definitely starts. it worked out for me. and it will also for you
