Hi, my name is Tim & I'm looking for some help. I am looking for an electric powered ATV 4 wheel drive 4-wheeler. I found a 1000 W Extreme xs but, they quit shipping from China for some reason. I do have a 1999 Yamaha 4x4 Big Bear 350 cc that only has 700 miles on it that I might want to convert or have converted. Any help would be appreciated. Thanks Tim
