my 650 was backfiring,so i took it in to have choke springs replaced and valves adjusted.i had 1254 miles on it. i get it back and take it to atv safety course ,also brand new no-toil air filter put in also.it started backfiring there and acouple days later it started doing it while at idle.i have to go back to dealer but do you guys have any suggestions to why this is running like this?
