My nephews 01 Raptor is making a loud knocking noise in 3rd & 4th gears(mostly third). I'm hoping it's a shifter fork but we don't have the books yet and I'm not an ATV tech(though I will probably be very involved in the repairs). Does anyone have any knowlegable input on this or has anyone else seen this problem and know what it took to fix it??
Thanks for any help.
