064 cylinder comparison

[Brewz]

Here is mine
Only 2 screw mount

 

[Brewz]

never was completely sure what the extra little box was?

Thats the multiflux reverse transmodufier.

 

[Brewz]

I measured the other jug with the damaged transfer.

No gasket:

103/124 to 126/73

both of the KS cylinders had progressive uppers with 2 deg between intake to exhaust side

That is a limited coil.

I'm not seeing that Jason.

The transfers really seem to be the deal breaker with AM jugs if you ask me. If you really study the tunnels, you'll see why. I don't think where the upper in rotational direction to the lower is the only factor at play in charge direction.

I have no doubt that the transfers are the deal breaker.
I hope to run them today,gotta build a saw to run them on first.

At this stage, I plan to remove the muffler baffle and open up the side outlet.
It is already running a well opened up dual port front.

Will rebuild the BING carb i have and fit that up. Im not to keen on the walbro 10A on it.

Do the 064's respond to a timing advance?

 

[Brewz]

That is a limited coil.

I bloody thought so.
I couldn't lean it right out.

Well I am not completely insane then.

You cant say you have not seen one now!

 

[Brewz]

My 2 cylinders are marked 1989 and 1991

I've seen one just not in person.

 

[Brewz]

what is seen cannot be unseen

They exist.

limited = yuck

I need a flywheel for an unlimited coil for this one now

 

[Brewz]

Ok Jay
These KS jugs look to be the goods.

What do we do with them to make them make an 088 look slow?

 

[jmssaws]

Is the flywheel dual key?

Doesn't take much for one to run good,it needs a little compression and a little more intake and a little less exhaust.

I wouldn't cut much off the base,030 or so

 

[Brewz]

I have 2 x 064's here

One I was saving for the 066/288 jug but I may put it together and run it as an 064 for a while.
It has a dual keyway flywheel, unlimited coil and BING carb.
I plan a V stack and VERY open muffler

what would be optimal timing to aim for?

I should be able to make a mandrel to cut a touch from the squish and sand the base.
A bit more off the base so I can make a thin gasket for it.
.020 from squish and .030 from base should work
What timing should I am for?

I wont touch the transfers.

100/124/75?

 

[Brewz]

widen the exhaust a tad and square out the base of the intake?

 

[jmssaws]

Sounds like good numbers to me.

 

[jmssaws]

This one is 100 123 77
Deets is running it and he will tell you how strong it is,the wood is rock hard.

 

[jmssaws]

Do I set all three cylinders at 020 squish or leave them alone?

 

[mdavlee]

Are they within a couple thousandths? .020" would be fair if some of them are a lot different

 

[jmssaws]

I didn't check them.
I'll set all to 020

 

[jmssaws]

I have a stock oem 064 muffler should I use it or a modded one?

Ignition advance?
