Back in August I began searching for a motor builder who would personally build race motors instead of sending it to some big company and just having a hired hand "build" our motors. well of course I looked on thumpertalk and found Williams motowerx and he had some great reveiws. Well we sent our 09 motors to him and all I can say is WOW. top notch work. Jesse has helped me from the start with any questions about jetting and motors in general. He really knows his stuff thats for sure. And as for his motors...WOW. if you are gonna have your motors moded make sure Williams motowerx is on the top of your list.
