Vespa + HPI Mini Rotor

Been a little while since i've been on here. I'm putting together a Malossi Ciao motor and I thought i would document what it takes to put a HPI Mini Rotor on a Ciao.

Anyone who's done this wanna chime in?

First hurdle was machining the posts flat. I'm starting with the Malossi Points case for my build. I was told that was the one that worked best with the HPI.

Here's one set of HPI's instructions: This one indicates to machine the posts to the same height as the center ring. The instructions that come in the same box as the ignition say to machine the posts 2mm below the center ring. Considering two of my posts were lower than the center ring to begin with, I decided just to make them flat (cut the tall ones to the size of the short ones)

That's all fine and dandy, but once you level out the posts, the provision for the crank seal (red arrow) hits the stator before the stator sits flat against the posts (white arrows). I used a die grinder to open the center of the stator to clear.

Next, the stator is cut for a 3 bolt pattern, but the case has a 4 bolt pattern. NBD - i made a template and drilled a 4 bolt pattern on the stator. I'll set the timing with the key-less rotor.

Stator Mounted with low profile screws to help clear the rotor:

now that i have the stator on, the rotor sits way too far away from the stator coils. I think the stator would still work, but it would work better if i bury the coils all the way under the rotor. To fix this, i ran some washers under the stator to shim it out.

alright, now we're cookin, right? well kinda. if i install the pulley and clutch (single speed) there aren't enough threads to get the nut on. So i measured across the motor from the right case half to the rotor, and sure enough, the motor is wider than the ciao frame is

Looks to me like i need to move the ignition closer to the case. that means i'll need to re-cut the taper on the rotor deeper to pull that in as well.

I'm gunna make this work, but I'm a little surprised there's this much work involved... It was easier to put a Honda ignition on a V1 than it was to get this together..

I've been debating how to cut the rotor accurately. I'm leaning towards making a cutter from a used crank

thoughts?
