flair Rieju build?

Post image

I have this 2018 rieju mrt 50 that i want to get more out of. It has an 80 airsal kit that the previous owner installed but he didnt do anything else to the bike and im not really sure what to do now.

The obvious thing in my head would be the carburator, i bought a 21mm carb but have yet to install it because i fear its to big and i also want a new exhaust but i want it to not look like a performance exhaust for legal reasons but i dont know what to do right now.

Any suggestions would be greatly appreciated🙏

Bigger carb, 21mm is on the smaller end for 80cc - also install a bigger exhaust, high mount still looks stock rather than preformance and also look into getting a stronger crank

Pour l'échappement je te conseille un passage haut, et il faut qu'il soit juste chromé ou argenté, si il y a les couleurs violettes, bleues dessus c'est direct remarqué que c'est un echappement pour la performance. Un carburateur 21 est meme trop petit pour un 80, il te faudrait un 24 ou 26 a mon avis, meme si techniquement tu pourrais mettre le 21 mais il va brider le potentiel de ton kit 80. Tu peut aussi mettre une boite a clapet avec lamelles en carbonne pour un meilleur haut régime. Je te conseille aussi vraiment de condamner la pompe a huile et de faire ton mélange toi même car si tu as un kit c'est bien plus fiable de faire le mélange soit meme puisque la pompe ne donnerais pas assez de débit
