I got my athena 50 on amazon for like 180. I think there's two versions, a bridged exhaust and an oval. I had the latter and it was pretty nice. Like a more reasonable stock cylinder with a very useable mid range. Theres a Portuguese site that has 44mm dt80 cranks and the big 100cc kits. I have seen some you tube videos of a dude ripping 4th gear power wheelies on the Italkit.
