My xplorer is running a little rough, it acts like it is lunging forward, or like something is hanging up and causing it to hesitate. Has this happened to anyone else?

Seen ike engine issues? If so, check your filter and jetting.

Could the ETC have anything to do with the way the quad runs? My cable is adjusted as far as it will go without replacing it. I know when it needed adjusted, it would run rough at certain rpms.
