It sure is interesting to see how the 441's reputation is changing. Like you mentioned, it's been fed to us that it doesn't take well to mods. I had the same experience with the little Ryobi/Redmax strato 40cc saw. It responded tremendously well to mods. The 362 did good too. What's not to like?
At first, I would have been happy with the 441 responded equally well as the 440 to porting, since they are the same bore and stroke (50 mm x36 mm). But, the 441 performs as well as a modded 460, which is 6.5 cc and 2 mm of bore bigger than the 441. That, to me, is pretty amazing.
Great tests guys!
In regards to the 441 being able to retain its torque better with the 9 pin, were both saws ported with the same intake duration? The reason for the question is that with the extra intake flow area of the strato port, a strato should theoretically be able to flow more air with less duration than a single port - thus a slight reduction in intake duration could give the same flow as a conventional engine, but with more ability to retain torque.
When we lowered the jug, we did reduce the intake duration.
Nice. This makes me want to get a 441 and port it even more. But, I'll port it a little different.
