Over the years I have developed a couple of engine builds that I think you will find interesting and unique. One of them is a based on the Honda TRX250R and another is based on the Yamaha Banshee. Both of these builds do one thing important - they dramatically increase the bottom end power and drivability of the engine. If you're searching for bottom end power on your machine look no further.
