309 Machine's CNC Ported HP500i is the ultimate mix of power and lightweight. 

HP stands for High Performance, and that's what we are all about. We strive to maximize power while focusing on durability and reliability.

This is for the Power Head Only (PHO). 

Performance work includes;

  • CNC Cylinder porting
    • Exhaust Port enlargement, timing and polishing
    • Squish band cut for smaller combustion area
    • Base cut for increased compression
  • Port matching, baffle thinning and hole enlargement on muffler
  • Removal of compression release

309 Machine recommends the addition of a performance exhaust and air filter to truly unlock the saw’s potential.
