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. We offer products for both of these from Westcoast Saw.
The stihl MS500 saw that I got from 309 machine exceeded every expectation that I had and wanted in a saw.
309 will be the only place that I'll buy any chainsaw from

4thgenfaller’s new 500i
My 5th 500i and by far the best! Very responsive, revs proper for limbing or brushing, snorts and growls at an idle and screams like hell in the cut! I cut old growth all day ground 3/8ths chain on a 36” bar she had power to spare, love it!

Great running saws, I bought two, cut some 6 foot cedars here in SE Alaska with them, they pull a 36” full comp great.
