First of all new member here. I bout a 2014 yz450 about 2 days ago. This is my first 4 stroke after 7 years on 2 strokes. My question is that the motor seems a little noisy at idle like a ticking kinda sound. I did the proper break in. Maybe I'm just not used to the 4 stroke sound. Just curious if there's anything to be concerned with. Thank you.
