The first ATV to finish the Dakar was a Yamaha Blaster 2 stroke. I bought a Dirt Wheels magazine just because it had that article back in the pre-internet days where rally coverage came in such 1 page magazine blurbs 4 months after the fact. I believe the rider was a Frenchman. He had no support, but the Yamaha bike team took notice and lent him tools and such from time to time. The engine held for the whole race but the frame did require some welding along the way. He kept the oil injection intact and carried spare Yamalube.
Your cycle had a bell on it.
