Thats what I noticed. Would take big wood and long bar to tell
the difference I would say. That wood they look neck in neck.

20" of wood the results will be different. In small wood not
going to be much difference. I noticed that with the 11" cherry
log.

The times were as follows. I timed each video twice. To try and
be accurate.
665-
Cut 1- 4.0 and 4.03
Cut 2- 3.7 and 3.75
Cut 3- 3.69 and 3.60
Cut 4- 3.60 and 3.65
681-
Cut 1- 3.0 and 2.9
Cut 2- 3.07 and 3.09
Cut 3- 2.94 and 2.96
Cut 4- 2.81 and 2.74
That saw in 65 cc form is a strong saw. With a 24" in a 20" Cant
at the last GTG it pulled solid 17-18 second times. There was
saws much bigger (460, 660, etc) that were between 15-17
seconds).
The 681 picked up about a second over the 665. Which is about
par for the increase in displacement. 16 cc was added (about
25% gain in cc).
The 665 only had about a half dozen tanks on it. Where the 681
only had a couple heat cycles and a few cuts (half a tank).
I was pleased with the results and my next test will be in a 20"
Cant.
Solo 665 takes down another woods ported saw stihl 362 c-m. All
of Dex info in the stihl thread above.
Dex times them from video. Also stated 2.5 tanks through the
665 and 5-6 through the 362 ported by mastermind. So none are
broken in. But the 362 is woods ported.
MS 362C-M
1- 6.8 sec
2- 6.1 sec
3- 6.2 sec
Solo 665
1- 6.2 sec
2- 5.7 sec
3- 5.5 sec

Those Solos are very, very impressive saws! As the old adage
goes, there's a lot to be said for German engineering. I love
the looks of the Solo 665/675/681 series of saws, too.
