What variator? Stock or something else?

The belt rubbing the cases and ripping out the oil pan gasket is not unheard of (it happened to me, more than once) but generally only with an aftermarket variator.

Oh, and it's more likely to happen on a fresh belt as well, since it is nice and wide when new and can climb up the pulleys better.

One final question: did you have the thin 1mm washer installed between the inner bushing and the outer variator, as is proper? Without that 1mm washer, you're almost guaranteed to have this problem if you ride WFO.

See: I know what the washer is for! A WARNING to J Costa Owners!

That would definitely do it. Without the 1mm washer in that indent, the outer pulley half will be closer to the inner pulley half, and at WFO that will cause the belt to climb high enough in the pulleys to start eating the engine cases.

And that's exactly what happened to me in the thread I linked to above.

My washer was stuck to the outer variator half when I took eveything apart the first time. When I went looking for it on reassembly I found it on the floor. It must have fallen out of the indent when I moved the variator half around on the floor...

I can't believe Piaggio doesn't make the case slightly larger to eliminate this from happening. Why take the chance on a tiny washer solving the problem? I've heard of the same thing happening with stock parts and everything installed correctly. The oil pan gasket sticking out just a tad much can cause and oily mess when it gets nicked.

This problem is very rare when the stock variator is correctly assembled with the washer in place. And realistically, in the worst case scenario, the penalty for not correctly assembling the transmission is fairly minor: one gasket and one belt.

I had 2mm of gasket sitting proud of the case lines when I put my DP variator on for testing, so to give a bit more leeway I took it back to the surface level with a sharp knife. Now, no gasket for the belt to grab.

If you mean though how to repair a broken gasket? Besides replacement?
Threebond (used correctly).

No. You'll lower your top speed.

It's fairly special. It's thinner than most washers and has a hole sized to fit over the crank. You won't find it at the hardware store.
