7300 cylinders
« on: January 24, 2014, 03:22:23 pm »
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.

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
Dan

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.
