Son weighs 75lbs on his blaster with a FMF exhaust and honestly dont know what motor work if any is done. All I know he smokes his cousin on a Honda 300R with a pipe also. He has holeshots on there now and has never gotten stuck at Pismo or Glamis cause he's sooo light. But will paddles work better for his set up and if so which ones?

 

I ran 8 paddle haulers on my son's blaster,it made a huge difference over the holeshots. I would say either 7 or 8 paddle would do him good. If the blaster is just piped ,7 paddles .With some port work 8 paddles would do great.
