Description

Ultima® has made a change to the line of competition series 100” motors. If you are in the need of a new motor and you don’t need a monster, we have what you are looking for. The 100” motors are a great replacement for a tired stock motor but still have great performance. Ultima went with a milder cam and lowered the compression. They start very easy making for less wear on your starter and battery. The milder cam makes for an extremely quiet motor.

  • Raw aluminium case with chrome covers
  • Forged dome piston
  • Camshaft: 262 Duration .520" lift
  • Single-fire ignition included
  • Includes Ultima R1 Carburetor
  • Billet oil pump
  • Compression release valves
