  1. Express 400 odd sound/vibration

    ATV Repair and Maintenance
    I have an Express 400 with only 1,300 miles on it. Lately an odd sound/vibration feel takes place - usually at higher RPMs while going up hill. Nothing appears loose. I can't for the life of me figure out what is causing it. Sorry I cannot offer any more information, but does anyone have any...
