Is that trooneys 661?

Yes

 

[dolmarkid]

Woo hoo how much compression does yhe 044/046 bb have

 

[Manofstihl066]

Yes

Do you think it would pull a 32" with an 8 pin in hardwood without any loss in torque?

 

[Deets066]

Smooth........

Wow, must be balanced

This is 404 full comp and hard ass white oak.
It's just a little ahead of a strong 395 with the same bar and chain

Way to much.
It's hurting it, I should have checked compression before I cut 020 out but the chamber looks the same size as the oem and I wouldn't think the bigger bore would make much difference

Or.......it could be the boxer style opposing pistons.

230lb right now but I'm going too try and loose 40lb

The oem hybrid is 185lb and a mile ahead

 

[jmssaws]

That 661 isn't even 185lb

Well yeah, it's a law of motion, "for every action, there is an equal and opposite reaction"!!!!!

That's a strong saw for not having that much compression.

The cranks probably should be balanced to the flywheel.

A larger bore lowers compression.

I started with the cylinder on that saw at
102 127 78 200lb and it was a stinker.
I've raised and lowered as far as I can and it just kept getting stronger everytime.
Seems there the exact opposite of any other saw.
The exhaust and intake durations are giant and the more duration the more grunt and overall power it gained.
Silly silly

Both of the 044 hybrids are @David Young that he sent me to R&D on

Thanks David

Where did your whiskers go?

 

[jmssaws]

Where did your whiskers go?

I was trimming up and it went bad.

It just keeps coming back though

 

[RI Chevy]

Start fresh. Lol

That field reminds me of my buddies and we built a small MX track. I would race my modded Yfz450 against his 250r. It was about a 1/4 mile long

I just finished putting a 046 54mm bb on a 044 and the piston was very heavy but I ground it down to size.

I have a full circle crank for a 660 that's very heavy and you can't tell any difference in vibs.
I have built some 064s that were likea jackhammer.

Ground down to size?
