Hey Everyone, just wanted everybody to know the conversion kit (6.5 HP engine kit for my Doodlebug) from Chris is perfect. Everything from fast shipping, instructions, parts, customer service, ( I called Chris several times and he was a great help ) I am not a mechanic and I'm not good with these type of things etc but I did the entire engine switch myself. My DB now screams down the street and it climbs hills with ease. I'm 6' 230lbs and it hauls me around no problem. Thanks Chris! Rex
