Technologies are reasonably mature. if you're getting a 60 c_c saw a smaller case it's lighter but it carries less fuel and less oil.
Dolmar do have a working prototype 4 stroke chainsaw in the lab, but it would cost too much at market right now is the story. ....
I disagree. The 5105 is an awesome 18", capable 20". But you jump 51 to 64cc and to a saw that is a died in the wool 24". You don't have the gap of a super strong 20, capable to 24" that is more nimble than the 64cc. For example, you have the 562xp and the 365.
Right now? Are you referring to the one they made a decade or so ago?
That one suffered severely in the power to weight department - so it was no surprice that they chose to not market it! opcorn:
Don't you say that about every saw that isn't a Husky XP?
..... .
Honestly who is plugging every 2-4 inches of bar size??? If I'm going cutting I'll take my little ported Makita 401 w/ 12in bar, and my 7901 with 28in bar (maybe a 20 depending on the cut area). If those two saws and 2/3 bars can't take care of the average wood cutter you got something wrong in your noggin! I usually don't even pull the 50cc saw out anymore! It's just one more saw in the way; unless I have a buddy cutting with me.
562xp is about the same case... I would toss a 24in bar on it and use my makita 401.
I run a 420 16" then next is the 6400...
I'm looking for a saw for 20" bar to complement the 420 and take some of the load off the semi retired Alpina 700. After buying the 420 I pretty much quit the idea of buying a 50cc saw.
Same bore 47mmI looked on the Dolmar sight and couldn't the bore and stroke specs for the 6100 vs the 6400.Would anyone know?
2 mm difference in stroke?So where does the difference in displacement come from?Pin placement,piston height above pin?It was my understanding that the 6400 makes it's power from a long stroke and a narrow bore.I'm befuddled.Now the 6100 makes .2 less HP,I know HP is to thunder(just the noise) as lightning is to torque(does the work).I'm missing something for these two to be so close yet so different.
3 cc difference is from the 2mm stroke difference...
Pie x radius squared x 2 divided by 1000 per cc
There you have it...
Are you sure?

With that said it's going to be hard for dolmar to beat the 362 and 562, but they've done it before.
