porting a 064 hybrid.

[Miller Mod Saws]

98 118 82

My vote would be even higher on the exhaust. But i guarantee tree monkey will know long before this guy!

 

[jmssaws]

I'll start there,I can always raise but it harder to go the other way.

Cookie cutter?

Yep that's about all I build anymore.
Work saws are boring and for work,yuk

I'm open for options,I don't build many 90cc saws for 16" bars.

Huh?

 

[tree monkey]

I don't think I would go more them 83-84 on the intake

 

[jmssaws]

Yeh I don't like much intake duration.
I'll fill it and start at 81 or 82.
Raise the exhaust to 98 and start there same with the mains at 118

my pipe saw is at 95 and that's to high

 

[jmssaws]

My 066 will tune well over 14000 and it's
101 118 78

 

[jmssaws]

My other one is faster at 100

How does the pipe affect it in terms of exhaust height?

Don't sweat it jms. Anyone that reads forums knows slow saws and chains are in Ohio. Lol

I thought Ohio was where the fast wood is?

 

[drf256]

J,

Why the 118 transfers when your 66's like 14-16?

My saws aren't race saws so I can't compete but I'll race if you want.
My fastest saw cut timber 6 days last week, I didn't think it would last but it's right as the rain still.

My fingers open at 14 mains are 18

without the pipe, on muffler it's slower then stock. has no torque.
iv'e made 4 pipes for that saw, the fatter shorter pipe is best, but I need to change my porting a little

 

[jmssaws]

I don't know if I'll do fingers in this one.

Do you run more blow down on the pipe?
Say transfers 120+

 

[drf256]

What's a higher vs lower transfer (numerical) giving you here?

 

[jmssaws]

I honestly don't know.
What I do know is the higher they go the better they run.
