80cc Cylinder G4

I found a recent vid on YT on this jug. it has different T ports, not like mine.

sad, it's already outdated by the G5 iron sleeve from BGF

That jug is odd. Did you notice the cylindrical casting on the right side? My g5 has them on the left and nicer. Transfers look different like the taller one is narrower.

Don't think the g4 is outdated at all. The g5 has no retaining ring on the sleeve so it could drop.

Ya that's the one. I have one of each. Personally the G4 looks better to me. I've tried watching that video at least 10 times and it always freezes about 10 seconds in.

Like Chris said, it is.

I have the g5 sleeve cylinder. Took a fair amount of work to make it right and mine is filled on the intake side since it's a case reed. Still a very nice piece.
