Have a shop load test your battery. If ok, then its most likely a high amp draw. If you take the quad in and they can do an amp draw on the starter as well. (all assembled)
thanks ima try and check the amp draw on the starter

Just got this atv 1 month ago the guy said everything was fine with it no problems i used it just to make sure everything was going good. I bought it and brought it home next day turned it on with no problem but i noticed it struggled turning on for some reason it seems like battery is not powerful enought to turn over the starter. But later turn on after trying 5 times left it on for a while. 2 days later tried turning it on nothing hooked it up to a charger for a min tryed turn in it on and turned right up. Well i thought to myslef its problably the battery not holding charge went ahead and bought a new one. But problem wasnt solved. I thought it might be the starter bought a new one put it on battery didnt have enough power to turn it over again went ahead and put the old one in and connected it to the charged turned right up again. Has someone had the same problem help plz. Battery voltage drops to 12.23 volts and doesnt want to start it struggles hook it up to charger and fires right up. How many volts does it need to have to fire up. Help plz
