Husqvarna 550xp mk 2 and 572 xp cutting some firewood

Both mildly ported saws with stock timing and base gaskets. Muffler mods.
550-20” cannon bar .325 .050
572-28” Oregon bar 3/8 .063 Stihl hexa chain.
I finally got my 9 pin .325 sprockets for the 572 so I will be uploading some videos of it running the 20” and 28” cannon supermini bars , hopefully soon.
