Just got my Stella engine back after a rebuild and many mods by Gickspeed; including a Pinasco Flytech ignition system https://www.sip-scootershop.com/main/base/Details.aspx?ProductNumber=25356831&_language=en
I am running an all DC electrical system on this scoot with a Trail Tech Regulator/Rectifier, which requires a floated ground in the stator of the Flytech - thankfully, I found this awesome thread on how to modify a Variatronic stator, which is virtually identical to the Flytech stator. http://www.ilambretta.co.uk/forum/viewtopic.php?f=7&t=4551
The only difference is the Flytech stator does not have the wiring buried in electrical potting compound/resin, but instead has a small connector that secures the wires. This difference makes the job much easier. It was a bit nerve wracking to modify a brand new and expensive stator, but all works perfectly!
