Well, most engines we worked on were split for the first time, but there were cases with faults from the factory and they had no problems. We just spread a bit more sealant on the problematic areas. The best thing about this sealant is since it's anaerobic it doesn't start to cure till you tighten the cases. And easy to clean up...

So you can't put too much on, is that what you're saying?

Very cool tidbits! If a company spends all that time to make their own axle shaft, loose gears, and shift cross, would it be worth it to make a cruciform with 6 legs? I'm just wondering how much more durable it could be.

As a newb to Vespas, I am confused about what you can and cannot put into these cases in terms of gearboxes, cranks, piston kits, etc. I know there is a rotary and reed valve version and that is reinforced in certain places.

I'm assuming that late PX gearbox internals would have to be used, but what about cranks and cylinder kits? Could a 200+ cylinder be used? Are you stuck with using Malossi performance stuff, or is it anything goes?

Besides the reinforced areas, how does it differ from the Malossi "stock" case or the Pinasco case?

Thanks and apologies for what is probably obvious for most enthusiasts.

I wonder what the go is with that drive shaft and the large bit of casting in the middle?

They needed a flat surface for the malossi logo. For when you split the cases and have a crowd of people watching. chaching!

(a) Anything goes (as long as you're willing to deal with the inevitable issues of making parts from various manufacturers fit together). For an example (shameless self promotion), see here: Building a "Boss Hog" engine

(b) Original Piaggio cases were built to a price, and they have every bit of metal they need and not a skerrick more. When it comes time for porting, and upgrading, they can often have air where you'd like metal. The Malossi cases are built more to a standard than a price, and they have lots of shiny metal to hack off in the places you want to, and plenty left over for strength.

Thank you.

That makes sense. Seems somewhat like VW type 4 and probably many other engines. Even with high quality aftermarket parts there is a lot of measuring and hand fitting. Cheap parts even worse. Things that will cause unintended wear and possibly even catastrophic failure unless you know what to check. So I'm imagining it's not LEGOs. I will read your thread. Thanks again.
