Just picked up a cheap 50cc 2004 model 4 stroke I want to fit my 125 et 4 engine in I had sitting for years.
I have tank, loom, coil most likely rectifier.
Can I splice into the old loom as not worried about changing instrument cluster.
Any schematics on this technique if anyone has .
Or will I need to use the 125 loom.
Not sure if this one has immobiliser fitted or not and is it easy to bypass.

Mechanical stuff for me is fine but I left electrics in the days of points and condensers 😊
Anything I may have forgotten that could be of use.
I have found a few useful tips on the internet but nothing on electrics, just a mention in passing by Robot on Vespa West on youtube about a friend who is doing one.
Any help much appreciated
