Agreed but when removed it's just like an old saw before strato.What a dang contraption....

Welcome back. Hope all is well down in your neck of the woods.I'm not 100% sure.....but I think it gets really hot, and burns off hydrocarbons in the exhaust.
A lot of the work in this build is getting rid of it though.

I've thought about that too.....but just ain't buying it. I really think it's about emissions....
X2. I'm going to haft to reaserch this helm Holtz chamber. But if it's acting like a piped saw. Would that explain the shorter blowdown in the 7910 over the 7900? Good thread guys keep it up!Good stuff........
It's a good day........cause I learned something new.
It is just a fancy way of stuffing the exhaust up so that fresh mix doesnt escape out the exhaust was always my thought of what it did just looking at it but @jar944 knows more than me and after reading what a Helmholtz chamber was i am rethinking how it works and its effects
In some two-stroke engines, a Helmholtz resonator is used to remove the need for a reed valve. A similar effect is also used in the exhaust system of most two-stroke engines, using a reflected pressure pulse to supercharge the cylinder (see Kadenacy effect.) http://en.wikipedia.org/wiki/Helmholtz_resonance
So.......is this a performance enhancement, or just a emissions device? Is the volume of the chamber sized for a stock saw? If so, will it be too small for the output after mods?
strictly emissions/fuel economy. Though correctly sized it shouldn't hinder performance.
Its not functioning like a performance pipe. Its just there to "shut the door" on the exhaust port.
