It would make a great sidewinder motor....Im reducing the price to 1200$ and the carbs im still wanting 300$ for it, all i know about it is that it is a flatslide and it came off of a F3 honda motor....dont know who they were made by buts its in great condition also.....if u have any questions call (812)361 2345 i will answer all the question u need to kno - Thanks
