I picked up this little gem awhile ago and the 6401 runs alright and its a fun saw to play with! Torquey low end and mid range power.It's pretty much stock accept the muffler modification.

Nice saw old son, where did you get that cool Mobil1 sticker? :greenchainsaw:

Looks good from here....muffler mod must have really helped.

 

[daemon2525]

cool

Nice cut!, Basswood is a very soft wood though.

isnt that the saw that had a bad piston on it or something?

JohnDolmar:

Since you've got some 7900s also, how would you compare the performance difference between the 6400/6401 and the 7900, assuming both are running modified mufflers?

 

[Sethro]

6400 vs 7900
I like both.In smaller wood the 6400 will run right with a 7900 anything over 18 inch's or so the 7900 will walk away from a 6400.I wasnt planing on getting a 6400 because if your going to pack a 14 lb saw around,then whey not get the bigger cc saw.But the price was right.I have a 6401 tore down right now,it should run good when done.

2-7900's
2-6401's

I dug out a old Carlton square practice chain and touched it up today, bolted it on a 7900KD and made cookies.

Here is a clip of that 7900 that Ken Dunn done on a pipe.John :01.90

DAMN! Good thing I didn't blink, I would've missed something.
AWESOME saw John...
I tell you what, the more I use this 6401, the more I love it. Just got in from the backyard playing around with some 20" firwood...Butter baby! BUTTER!

John you are making me want to go to the closest dolmar dealer and purchase a 7900, they look strong, i wish these clips had sound.

 

[Sethro]

I like these saws.This 6401 only has the intake/exhaust ports widened and muffler opened,lots of torque,now it needs more crankshaft revolutions per minute.

lto,yep I need a camera with a mic.

 

[Sethro]

Ron,I really liked your factory looking muffler mod.I went for the same approach on this one.Instead of uncrimping these Dolmar muffler I go trough the back with a small pneumatic saw and cut the cage out along the exhaust bolt access tubes then clean it up with a carbide bur.
