Looking to swap in a gpx/piranha 140 or 150 into my sachs madass. This bike has a 3-phase stator and electrical system to power the big headlights. It seems I will have to swap the stock stator into a new engine in order to be able to keep all the current lights working. On the madass, the stator is bolted to the stator cover. The e-start yx 140/150 motors(piranha, gpx) look like they have the same stator cover on them as the madass. Will the old stator easily fit into one of these new engines? If not, I might just replace the whole system with lower power lighting that these motors can run.
