Motorcycle and Scooter appreciation

Scooter question: is there any good reason not to use Castrol A747 two-stroke oil? I've heard some people say it's just a decent, nice smelling oil, others saying it's for racing only, and shouldn't be mixed with even a drop of synthetic. Need to make up an order from SIP.

Remembering the words of my Canadian friend Francois Lemabre, "fuck it, it's only a Vespa"

Buy it. The Vespa motor is designed to run with almost any old shit as the 2 stroke oil. In the early days it would have been regular 4 stroke motor oil, then EssoMix (2 stroke mix straight from the pump). Fully synth reduces the need to decoke the cylinder head quite so often, but on a Primmy/ET3 motor such as yours it's not essential.

Incidentally, check with Ben in case Project 14 re-used anything, but I have an entire ET3 ignition system surplus to requirements now that is for sale; flywheel, stator and Ducati CDI
