I just picked up a new to me 2016 and was wondering how do I know if it has a tune or not.Bike came with Vance and Hines cs1 exhaust.Bike seems to run great,smooth power and no backfiring.Would the bike run crappy if it didn’t have a tune? I haven’t seen if anything’s been done to the air box yet and not sure if the cats been removed.Anyone have pics of what the cats look like? Even though the bike runs great I’m worried I might do damage if It doesn’t have a tune already with the exhaust. I asked at a Yamaha dealer if there’s anyway to tell and they said there’s no way of doing so.I also have a dragon emblem on my clutch cover.Does this mean anything (like some type aftermarket part)? Any help is appreciated. I’ve got to say I’m loving the power of the Vmax.Makes some of my of my previous bikes seem slow (2 gen1 fz1’s,a gen2 fz1, and a zrx1100).
