I have a 2012 rotax max built by Ogden USA. It has had 2 top ends and 1 complete rebuild finished 3rd in the 2012 florida winter tour in the tag class. Currently has 7 hours on top end and 17 on bottom.
It is sealed and includes passport I ran it on a 2012 merlin lm-30 chassis which started front row at the 2012 robo pong I am the second owner of chassis and engine. If you want both engine and chassis that could be done for $4000
Engine also finished 3rd at the rock island grand prix. In my first race ever in tag I was .011 away from a track record. That is an indication as to how strong this engine is
Let me know if you are interested, have any questions or would like to see any pictures.
