I got this quad a few days ago and resolved a few issues now I have a new one. Yesterday I cleaned the K&N and reoiled it, reinstalled and test drove it. Working great. Go for a ride today and after 5 min it bogs down and will only idle. I let it idle for 30 sec and all is good. I decided to keep going and rode for an hour with no issues and then it did it again. Same thing, give it 30 sec at idle and all is good. It did this 3 more times on the way home. It also seems like it was backfiring more but I may just notice it more now because I am listening for a problem. thank you
