The world's best CNC ported Stihl MS661C. Don't wait 8 months from the other guys, get the most advanced saw available today.

This is for the Power Head Only (PHO). Add a Stihl lightweight bar and chain separately.

Performance work includes;

  • CNC Porting on cylinder 
  • Port matching, baffle thinning and hole enlargement on muffler
  • Removal of compression release
  • Oil pump adjustment modification for increased oiling capability (needed for 32” or 36” bars)

309 Machine recommends the addition of a performance exhaust (WCS Bark Box) and a performance air filter (MaxFlow) to truly unlock the saw’s potential. 

We are also working diligently to procure saws as fast as possible. If a saw shows in stock, it is on the shelf and will ship within 24 hours.
