Chevytown's 365 "Super Sport" Special Build

[CHEVYTOWN13]

Cool frijoles Matt.

It's looking like I might do finger ports on this one after all. But I'm not sure yet as I ran into a thinker.

Not as bad as I thought.

Here's the deal on the fingers. I'm not sure what to do about this area yet. This will have to be machined if I even have a chance at fingers.

Then I think I have a shot at small finger ports. And like the Kita, 6 transfer ports total.

Black coil unlimited

Blue coil rev-limited

Will be watching to see your 6401 and 365 comparison

Rick, with the 371/2 cyl, flywheel side, the outside of the transfers have been "pushed" in. If you look inside, you'll see that it protrudes to the inside of the transfer. I grind to match the opposite side.
Not sure if the 365 is the same here.

i wouldnt mess with the finger ports. youl just build it cut a few cookies sale it then its going to grenade on someone as there trying get wood cut to heat theyre house thinkn they just bought a bad as mo fo finger ported saw

 

[CHEVYTOWN13]

Al, I'm going to have to check it out. I think I'm going to machine that part I spoke about, but I have to ask the big guns up yonder. My guess is yes.

Why is it going to blow up? All finger ports do is add extra ports for more flow:monkey:

 

[Evan]

who knows. i for sure dont.

just seems like theyre would be alot more finger ported saws in the woods if it was common reliable mod to do

 

[CHEVYTOWN13]

You're barking up the wrong tree

That's a double :monkey::monkey:

Been reliable here on the West Coast for some time now. And if Tom uses them, I'm using them

I'm not sure where you're getting at, like Paris, but I could care less. Someone's going to have a good firewood saw

 

[AUSSIE1]

I take that area down Rick.
Good enough for the 385/90, good enough for me.

 

[Evan]

thats cool. i never even heard of finger ports till you did it. not even with 2 stroke motocross bikes but like i said i dont know im just a punk kid that doesnt know anything.



i guess its more common then i knew about

 

[AUSSIE1]

Also Rick, if you look in that top transfer, you can see where I ground out the outer wall.

 

[AUSSIE1]

Rick, the photo with the texta mark, have a look at how much protrudes beyond the gasket (transfers).
This is what's hanging over in your transfer area of your crankcase.

 

[J.Walker]

Alright, cleaned up the best I could and ready for a tear down.

Here you go Easy E, for your viewing pleasure

I'm sticking with the limited coil. Not sure what type this one is. Research time later.

Like the photos of your 365, good thread!

I bought a new 365 about a month ago. It's still in the box.
Had some ideas that I need a 4 cube race saw, Some thing faster than the woodsported 357.
At first thought, the 365 was going to get a 75cc p/c put in, but that would have been a cheater saw. So i'm staying with the oem p/c that came with this saw.

And that's as far as I have got!

 

[CHEVYTOWN13]

Al, good stuff mate. Thank you for the pictures. That's a big help.

I'm studying the jug for now. Everything looks to be in good shape. So I have a good amount of time to port. I'm taking it slow.

Cool deal Walker. One thing I noticed about the Husq are the HUGE case ports. Damn.

 

[AUSSIE1]

Yep, take your time.
Tomorrow you'll see something you didn't see today.

 

[AUSSIE1]

I've actually got mine apart again as I'm increasing the durations as per a piston change, ready to be assembled.

 

[CHEVYTOWN13]

Sounds cool Al

I also have a p/c that came off my 2171 so I have been checking those ports.
I think my saw will have a pop up or turned piston.
Carb and intake maybe changed too.

This new saw is never going to cut firewood!

So what's the plans here J?
Whack the 2171 cyl on the 365?

Well it is tempting to put a larger p/c on it but thats cheating if I'm running it in a 4 cube class
I could do it anyways and just call it a pratice saw tho.

Going to stay with a one pc. head.
Gas only
No pipe

Going to have someone else build it.
I just want to race it at some small town races and GTG's.
