Just picked up a used 2005 patriot yamoto 50cc. It has been sitting for couple of years. It did not come with a user/repair manual. Looking for suggestions for oil type/capacity/ spark plug gap and recommended brands, any place I might look for user/repair manuals. Other things I need to check to make sure it is safe for kids. Any known problems to be aware of? I'm new to the ATV seen. Any help and direction will be greatly appreciated. Thanks
