My atv is backfiring when decelerating from higher speeds (35-50 mph), any idea what is causing this. I just had the valves adjusted, is this the problem.
I am going to take it in next week to get the problem fixed but will it do any harm to use it until it is fixed.
As you can tell on a scale of 1-10 when it comes to mechanics, I rate about a minus 2.
Thanks in advance
