Update: finally took the variator apart, found out the brass bushing the pulley rides on seized, causing it to stay open. I pulled the clutch apart, replaced the pulleys with Treats' aftermarket set with the vented bushing. Replaced the clutch pads with a NOS Piaggio set and replaced the stock contra spring with a yellow Malossi piece. I was tired of dicking with old parts and basically just replaced everything.
Now when I try to put it on the bike it rubs straight on the frame, you can see in the pic where the back of the pulley is wearing a groove into the frame, and this is just from hand spinning the clutch. Apparently these pulleys are slightly different dimensions, am I unable it run these pulleys? Is there supposed to be a spacer or something in between the gearbox and back of the clutch unit to keep it from rubbing?
I've never genuinely hated a moped more than this one lol.
