Im looking to get a new quad. Ive been looking and came across the yamaha wolverine. Are the 2005 and older models good atvs? Are the engines strong? Does they break down a lot? Now before you answer i dont want the yamaha brand haters to come out and say "NO!! Yamaha is just a pos!" I want people that have riden the bikes or know people who have owned the bikes or have owned the bikes.
