I know there is a lot more to "wear" on a saw than just the piston/cylinder. However, this is a ported 359 that has seen countless hours of hard use over 10+ years and shows no signs of stopping or slowing down.

So, in my opinion......... there's always a trade off for everything. Will it shorten the life of some components? Sure, to some extent. Will it produce more than a stock saw in a given time frame? Yup. Will it do it while putting a big smile on your face from the added power and pull of a larger displacement saw in a lighter package with lightning quick throttle response? Absolutely!
