Cameron Niemela is one of the most inspirational dirt bike restorers and has shared loads of amazing content about his projects and the techniques he uses for his rebuilds. I for one, love his channel.

Unfortunately, Cam is gravely ill, having recently being diagnosed with Leukemia. He desperately needs everyone's help and prayers. His family has started a raffle to help raise funds to cover a small part of his medical costs. The raffle drawing has been delayed to allow for further donations. Cameron's current state (as of this morning) is that he's in the ICU, so that you realize how sick he really is.
