Are those just extras you have or do they go to saws you are working on? For Huskies, Stihls or what?I have a preference for quad transfer cylinders. I started laying out a couple and got a little carried away. So I figure I might as well post up some pictures. Hopefully it stimulates discussion.

Nice, I will have to take a look at what I have, I had not paid that close attention before. Very cool!Some are slated for saws, some are just part of the collection. I realized I didn’t grab any 50cc. I’ll bring some of those in a bit.

That's where I saw some, got to work on two 372s...ok, I have worked on one!Perhaps the most infamous bottom fed quad in existence, the 50mm 372 OE.
Very nice thread @Ketchup ! This will also help folks that might try to run down the hybrid rabbit hole. Tjats another thimg we need, dimensions of bolt patterns of cylinder bases.
I just took some pictures of the dolkita 79xx OEM 52mm and BB 54mm cylinders and got on to share them, but see you have that covered already!
A continuation of the above post. This time looking at the shape of the transfer ports. As well as how they direct the air from the case into the cylinder.
The first two pictures are of the OEM transfers. The first picture is of the transfer closest to the exhaust port. The second picture is the transfer closest to the intake port. Note they both direct the air/fuel mixture towards the intake side of the cylinder.

Here are the transfer ports of the BB AM cylinder. The pictures are in the same sequence as the pictures above were.
You will notice that the AM BB ports don't direct/angle the air/fuel charge quite as quickly towards the intake side. Its definitely lazy in that department. Plus there's less directing the flow in general. All this can be fixed, but will take lots of time.
