In 98 & 99 I built a Hard Tail with a Shovel & 4 speed,rear chain drive. I later changed that to a 95ci TC with a 5 speed,rear belt drive. The Primary I used was a 94-99 Soft Tail, with a RevTech 5 speed,same years.Later I changed the engine to an EVO.Used the same Primary & Trans. The Primary was called a Primary in a Box,if memory serves me right.It was complete with all the parts for the Primary.
