hi everyone i just bought a 1999 honda foreman 450 and was wanting to change the oil so i was wondering what the best weight to use is and how much. one other thing is that every once in awhile it will backfire on deceleration i have ran almost a full tank of gas through it and put some carb cleaner in it i wondered if it was maybe a tight valve or something so if anyone has some insight on it help would be greatly appreciated thanks!!!
