Definetly NOT! Its a very pipey,very fast mx only moter. I rode one in 74 and I also want to find someone else to port another one. It was so much faster than anything on the track in 74...it was a real blast to ride. Im tempted to ask Carl if he wants to do another one! You should start with a later cylinder because KTM went with his finger intake port design soon after they saw it.

For Hare Scrambles I would leave the engine alone. Heck stock there isnt any other period bike that will out pull a properly running one.
