064 cylinder comparison

[jmssaws]

I've got a aftermarket 064 cylinder that looks good but time will tell,@Definitive Dave may know what brand it is but I don't know.
I'm gonna time it and a oem mahle and oem ks then I'll run all of them in the same wood with the same bar and chain. Hopefully it's timed well because the base is thick and will give more options for mods.

My money is on the Mahle

Is the aftermarket jug also a 52mm bore?

All are 52mm and all timing will be without a gasket.

 

[Chainsaw Jim]

Looks like a 54mm 066 jug.
That faint ring around the bore gives the illusion of it being larger.

I think the KS will be the best runner stock. Can you cc the chambers as well?

I think the KS will be the best runner stock.

I'm hoping so because I have one.

I'll rig something up and cc them

 

[jmssaws]

The mahle is
103
127 fully open at 129
73
Has a nice finish on the ports

I just try to get them level and put a plug in and fill with water from a small syringe or baby medicine dropper.

The ks is
104
124 fully open at 128
73

Finish is not quite as good as the mahle

Well.....so much for that being the best runner, trans are low as *s-word

You using a stock piston I take it?

I was just about to say ks for the winner with those transfer numbers. Match that exhaust to the Mahle and look out.

 

[jmssaws]

The aftermarket one is

97
124 and open flat
80
Has the best finish of them.

The transfer opening is almost twice as big on this cylinder which in my experience will hurt it but time will tell.

 

[Chainsaw Jim]

The aftermarket seems like the best one for cant racing mods.

Meteor but it measures the same as a oem

 

[jmssaws]

The ks intake is poorly shaped

 

[jmssaws]

The aftermarket also has a decomp hole which doesn't mean anything to me but to some it would.

Got the chambers clean and fixing to cc them. Just eye balling they all look the same size
