Here we have a Stihl 090 fully ported ready to make some dyno pulls.

This vintage Logging muscle saw, one of the biggest Stihl saws made.

070 fitted with an 090 piston and cylinder brings this beast to 137cc.

Porting adds even more power to this already strong chainsaw. Huge torque for long bars!
