Honestly, I dont care about having the more powerful saw, my dad has used his big saw about 3 times in as many years. I have realistic expectations of a chinese knockoff saw and I will probably use mine just as little.
I'm not going to slap Stihl decals on it and try to pass it off as the real thing. It's a project / conversation piece for me. I dont cut trees for a living, I just like chainsaws.
I will probably use this saw more for fun than for need. But if I can get a saw that will run a big bar for $200, then it is worth it to me. Not only will i get familiar with every nut and bolt, but it's still a big saw for very little invested.
However, with that said, if there were bolt ons, or easy mods, such as a top end kit, or power reeds ( or equivalent for piston port) that would make it run better than stock, then why not?
