You mean 500 series ?I would expect so. They are just the less expensive laminated bars or the 400 series saws.

Don't know of any specs; just a sugi bar with husky graphics.
That's what I was thinkingThe pics I saw looked more like new style Tsumura bars, not Sugi's
Pics ?The bars I have are Sugi's.
Wow, you still have ash there
Nice, did you leave a high stump for an excavator to take out or something? I always cut em at the ground unless they’re going to be dug outHere are the pics I could not load before (a big dead Ash in Carmel NY).
Seems to be a long delay in uploading pics.

There are a few alive here in the city that they sprayed, and I've found a few smaller 5-6" trees that must have been resistant because there were plenty of dead trees all around them. My buddy wanted me to take one out that was at his cottage, I explained what it was and he left it. I told him he should probably spray it as there was some damage on it, not sure if it will make it or not, but it was very healthy overal.Yup and some of it still alive too surprisingly.
Gasket delete (squish .020), widened exhaust, staggered upper transfers by slanting the roof with exhaust side opening first, intake roof raised a touch, cleaned up casting flash, muffler gutted with welded on deflector and larger mesh spark screen, intake baffle gutted out of intake manifold and carb shafts thinned. I got about 15-16% over a muffler mod with this stuff. If I had machine work done to it to raise the compression I would probably get another 5-10%. I like to test gain over a muffler modded stock saw because it gives me a idea of what the porting actually did for the saw. Some guys count the muffler mod into the total gain but that’s a bit unrealistic imho. The 572 performance is very good stock with a muffler mod imho.Nice! What’s all done to that one ?
Those are good gains. It sounds good, looks to run real nice.

I think so, was something like 5-10% can’t remember exactly how much. In bigger wood the difference is more noticeable. I do notice a difference with the larger weave spark screen vs the stock one in a modded muffler so the screen is definitely a restriction in itself too. I’d actually leave it out completely if I wasn’t cutting on state property. Stock looking as possible for me is better.Those are good gains. It sounds good, looks to run real nice.

Forgot to mention I gutted the fuel tank vent too.Gasket delete (squish .020), widened exhaust, staggered upper transfers by slanting the roof with exhaust side opening first, intake roof raised a touch, cleaned up casting flash, muffler gutted with welded on deflector and larger mesh spark screen, intake baffle gutted out of intake manifold and carb shafts thinned.
