Porting a chainsaw is done for several reasons, it all depends on what you want/need out of the saw. The most common is to gain power howver, you can also port for more torque and a higher RPM. This is done by altering the size of the combustion chamber (squish band) and increasing the size and shape of the transfer ports, exhaust outlet and intake.

If your saw isnt running well or is getting a bit old, it can be brought back to life with new parts and a service! All after market parts i use are origonal, OEM parts.

Chainsaws should be serviced once a year to keep them running well and to maintain their performance
