and the best scenario step by step instructions on how to fit on this moped

Don't.

Leave well alone, small engines r incredibly sensitive to changes in their exhausts, the bike magazines often test super-duper power-releasing de-restriction kits, & all that u get is a bike that runs like a sack of bolts, worse than it did before.

Use it for what it is. A poxy little screaming whingeing scooter. Save ur money for a better 125, do ur tests & throw ur leg over something with some real power. Nothing sounds worse than a tinny little 50cc hammering its' head off.

Well, Insomnia is right that it can be tricky; but do it right and it is quicker than a restricted 125. l got a new barrel, carb, reeds and exhaust for my TS50 20 years ago and top speed went from 28mph to well over 60mph. Cost around £200 and some help from a cousin who knew his stuff. Important things include getting the jetting right and running it in properly.
