Husqvarna 572xp vs. Stihl ms500i R, Both Stock

- Filmed in Late November or early December, I cannot remember which.
My saga started in the mid '70s as a teenager as an operator. Resultantly, there is some opinion in this segment. It comes from having operated many different sizes & brands of saws. A multitude of different fully stock, mediumly modded, and fully "worked" over mo-chines as well. Bar lengths ranging from 12 or so inches to 72 inches.
I've been waiting awhile to start this series. Mostly, I wanted the owner of the 572 to have a chance at running his 572 & 562, since they were the first two saws he had me do.
This 572 runs better in stock form than the early versions. A similar trait that we have witnessed in the 562s. I'm guessing that the fuel mapping has been refined in the last few years.
What "Super" Dave was eluding to was the general over weight aspect of the Husqvarna designs for the same class size of saw when compared to the Stihl model of the same.
As mentioned, they do not run the same as far as time. They do run kind of close though. I would say them have a similar feel in their power delivery. The 572 did nicely while giving up 8.63cc of displacement.
I "slammered" (slur + stammer) my speech it would seem. With the wind, it would seem that I said the 500's bore was 64mm,,, ooops...The 500i has a bore of 54mm and stoke of 34.6mm for a 79.2 amount of swept volume by the piston. The 572 is supported by a 48mm bore and 39mm stroke for the 70.57cc of volume, or 70.6 as the factory published numbers.
Both saw have an "A.I." system running the program.
Looking at the timed runs:
572xp at 12,700 went 12.23 down and 11.71 up
500i R at 13,500 went 10.49 down and 10.32 up
On average, the 500i was 1.5 seconds faster. We are looking at a ~ 20" cut, marginal chain. 1½ seconds a cut can make a big difference at the end of the day went an operator is making hundreds of them.
I'm currently available for custom saw modifications. Please shoot me an email if you are interested.
