Hey guys yesterday I bought a 2015 Polaris Sportsman made in USA 3/9/15 and the machine has a little over 2 hours on it. I was riding it around yesterday kicking around in my yard and today I notice some clunking when I go at a very slow speed or when I give it gas from a dead stop. Is this normal? It does not bother me I just wanted to double check and make sure everything is alright can it possibly be because of break in? I am replacing the oil and filter at 10 hours. I was going pretty fast yesterday on it.
