I've been following this thread for a while and happy to see recent updates.
I have a 2003 Genuine Stella 2T which is essentially a PX150 large frame. I attempted a full IC engine rebuild last summer and it ran great but something wasn't right with the gear stack. I had thought about going electric before the rebuild and now I'm ready to ditch the 2 stroke!
@resistor I'm super interested in your 72V upgrade. I've been eyeing a motor from Kelly - their 72V 6kW motor - which seems like a beast. I've also looked at the battery pack from Luna, but it is pricey and may not be powerful enough. Leaning towards assembling my own.
Just wanted to check into this thread and say hello. Keep up the great work!
