I have an AM Racing Engines Rotax Micro Max Engine. This engine won every race in 2013 at CMP and won the last two races of 2014 at CMP. It is a lettered cylinder so it is legal for 2015 and I have a brand new EVO upgrade kit to go with the engine. This is one of the best Micro Max engines out there. I saw one the other day for $15,000 this one is just as good and far less money. I will include the complete prevo kit (carb, pipe, wiring harness, coil) and the new EVO upgrade kit. Asking $4,500 OBO, Please call or text with any questions.
