Has anyone posted a step by step process for a Lifan conversion to a ST 90 ? I've read and I've read but nothing comes up as a step by step process, not unlike a recipe for baking cake. Some of the engines are listed with a Lifan No. such as 152FM1 which I believe is a4 spd. manual, is the engine I should be sourcing ? What about converting t 12 volt ? what is needed ? Thank for any and all help
