2013 Honda Rincon Stalling

I just bought a left over 2013 honda Rincon for a dealer out of state it has 50 miles on it from running from the garage to front of the dealership everyday since 2013. I noticed when I fist start it it never has a high idle when cold and when I try to put in gear it will stall unless I let it warm up for maybe 5 minutes. I replaced the plug and that didn’t help it. I just want to know if this is common? Do they usually have a high idle when cold? The rincon came with the 1 year factory warranty so im trying to figure if it needs to go into my local dealer.
