     Howdy,

   Thanks for the input. This is in the proto-type phase. I think I know how it's going to react when it actually gets strapped on to saw but, I don't know for sure. I'm going to be totally open for suggestions. I'm trying to develop products that deserve customers, and have those products stand on there own merit. It's basically the better mousetrap approach.
   In the current climate of product copying, the only thing that will separate you from the heard is innovation. Realistically, you only have about a 2-3 year run on a popular product before water gets cloudy with copies.  Copiers are going to copy. In recent years even the copiers are copying the other successful copiers.
   Time will tell.
Regards
Gregg

Well if you are open to suggestions I'd definitely keep the exhaust timing low.  Probably start around the old school 066 jugs of 164-166 duration.  166 deg of duration has the roof at 1.015" with 0.020" squish. 

1manband elaborated on what I was gripping about with the transfers.  Since the divider is taking up space you'll have to widen the ports.  Taking a mold of the Husky 395 transfers would probably be a good start.

And I'd make it a 58mm bore and stick with the stock piston design.  It's light and has good flow to the transfers.  Just make the skirt a little longer to keep freeport in check. 

Innovation is what will set your products apart.  Look at the HyWay 359 cylinder with the 357 style transfer ports (no caps).  Those are great runners out of the box but I think their platting isn't the greatest.

     Howdy,
   Pretty thick skinned here, so don't sweat it. Whether they are good, bad, or indifferent, all comments are welcomed.
