This depends on what is wrong with the starter motor or maybe just part of your ignition system. If you intend on changing your starter motor i can try help you step by step but the worst thing about bl**dy scotters is the body panels. The starter motor is fairly simple for an ametuer to change so no worries there, you just got to be careful. Once you've located your starter motor reply back to me in detail what it all looks like, i.e. Connections, bolts etc. as off the top of my head i cant remember what it looks like on a speedfight but if im correct i have a peugeot trekker that im working on at the mo. which i think is an identical engine so if thats the case then ill happily go through the starter motor change with you.
