Just had a couple of quick questions. Recently got my 066 big bore kit in from Baileys, sitting on my desk. I notice it has the black coating, and I wasn't sure if the 4th gen kits are supposed to have this black coating or not. I thought the earlier kits had it. I recently got an 044 BB kit, and it was not black. Also the picture online shows a grey cylinder, but not black like this.
I've attached some photos, they are crappy (from my phone) but hopefully showing port shapes and combustion chamber. Does this jug have the new combustion chamber design? Also, what is up with this intake port? Lots of intake duration i guess. Don't have the kit on the saw, so no timing numbers, but this is kinda different than any other saw i've done. But then again, this is my first 066. Heck, my 440 has wider ports than this.
What do you guys think, is this current generation? Or did I get an old one?
