This is the story of my '64 Vespa 150 - how it became mine and how it has given me a new vespatude. I'll be recording the neat places I visit, the different things I do to make the Vespa my own, and - oh yeah - those reactions I get from both friends and strangers.

Heebie is Frankenstein!
I think I may have figured out what is up with the electrical system. This email received from a guy at The Scooter Lounge kind of opens the door to what I think might be the answer...
I woke up this morning with a brainstorm about your scooter, looked at pics of your engine and confirmed my suspicions. I believe your motor is a p-series motor. This is a vespa model from the late 70's/early 80's. that's why the stator and flywheel electrical upgrade wouldn't fit. That would explain a lot. What is the VIN on the engine swingarm? I'm guessing it starts with VNX.
Philip at the Esso B's had already wondered if I perhaps had a P series engine in the scoot. However, I looked at the VIN on the engine and it was indeed a VBB2 engine. It even matches the original VIN on the Indonesian title I have.

The body is in very good condition. This appears to not be the norm for Asian scooters, but I have looked it over inside and out. There are no dings or dents on the inside of the skin or on the outside. There are also no seams where any welding has taken place. The engine was not in such great shape. When I went inside the thing you could see scars in the case from where something let loose in there! You also see a weld repair around the oil plug. There was also some sort of bonding agent around the drive shaft bearing.

What I think may have happened is the engine let go at some point in the scooter's life and really blew things apart. The body avoided some wear and tear because of the lack of engine power. However, my Indonesian "retorer" got ahold of it and repaired the engine. They actually did a decent job - it ain't pretty but it is solid.

The funky thing they did with it - I believe took the bearing housing and shaft from a P series engine and placed it in the VBB2 engine case. This meant they had to use a P series stator and flywheel. I am told this is possible. I have even read of people taking a VBB2 half of a case and matting it with a P series other half.

So, my guess is that I need to convert my electrical system to a P series diagram... I'm thankful for all the people who are trying help me with this and I'm sure I'll find the answser.

So the engine VIN is VBB2? this is really strange because the picture of your rear axle oil seal would indicate something different. Look at http://www.scooterhelp.com/tips/engine/rear.bearing.old.vespa.html for pictures. Is it possible your engine VIN is altered or that the swingarm is welded onto newer cases?
If your engine is a VBB clutch side case mated with a VBB flywheel side case, then your flywheel side seal will look like the picture at the bottom of this page: http://www.scooterhelp.com/tips/engine/fly.seal.old.vespa.html on the other hand if it is a p-series case like a VNX it will look like the one pictured here: http://www.scooterhelp.com/tips/engine/fly.seal.lf.vespa.html
I will draw up some wiring instructions for you to use the p-series stator.
