Does the Dolmar 7300 jug have the same open transfers as the 6400?
Anyone run one? Adam
-
7300 is like the 7900 cylinder Adam. Dan aka Dozerdan has a 7300 for sale right now too.
-
Thank Kevin. Did the 7300 come out before the 7900? Or were they all marketed during the same time period?
-
I'm only guessing. But thinking the 7300 7900 was same time frame. I remember seeing 6400 7300 7900 together. 6400 was only open.
Also Makita had them in 7301 7901 6401.

Whatcha thinking Adam?

I will take 400.00 delivered in the lower 48 for the saw with the 73cc cylinder. Add 35.00 if you want the 79 top end on it.
Later

Thanks kev! Adam, I was thinking a 6 transfer 52mm cylinder would be interesting for a stock appearing 5 cube. have to look at one of my 6400 jugs and see if there's enough material to bore that much. Adam
-
That is a October 2009 or later or at least has parts on it to make it look that way?
It would be hard to beat the offer of $435 for the 7900 cylinder on it.
The 52mm big bore doesn't have more power than a 7900 unless you port it?

Sounds like he's thinking of boring the cylinder out to 52mm.
-
I thought big bores were 54mm.
52mm is stock 7900
-
Was thinking of boring the 6400 cylinder to 52. curious how the 6 open transfers would flow on a race saw
-
If you bore a 6400 cylinder to 52mm, the open transfers will be so small that you will have terrible performance
To bore one of these cylinders will cost you $500 by the time you get it replated and finish honed
-
Under $300 to strip, bore re-chrome at Millenium. I think your right about the transfer tunnels getting too small! just did a little port wodo on a 6400 jug and noticed a lot of carbon from exhaust back flow into transfers! Anyone else noticed this? Seems like some more blow down is in order
-

Thats what I remember. Fit piston to your clearance specs too.
Never ran a 6400 let alone seen inside one, besides pics.

We can remedy that about any time!!!!
I have 2 6400's and can't forsee a time in the rest of my life that I don't have one.
They are GREAT saws, and drastically under-rated......IMHO.

sounds like you're at the limit of what that jug can do!

I forgot to remind you for the Poulan GTG, to bring a stock 6400.
