I bought my kodiak new 4 months ago and never had the vibration that you're talking about. Put a few tanks through it to break it in and if it keeps up I'd take it back to the dealer.
Are you familiar with the EBS(engine breaking system)? This could be what it is. If it's a strong vibration it might be more serious.
Go through your break in period and if it worsings call the dealer!
