Should be like a 3 second humm you hear as it primes when you turn the key. Then press the starter. I always wait until after the humm stops before I try to start. Same procedure on my Honda rubicon atv.
Might depend on how much gas is in the tank, if it is full it might be a little quieter due to the gas muffling the sound, I never paid that much attention to mine so I don't know for sure, just a thought for what it's worth
