I have a 2005 peugeot speedfight 2 silversport 50cc i put a tecnigas performance exhaust on it and it made it go a bit faster but sometimes came up to a junction and roundabouts after you stop bike wouldnt move and just bog down and take ages to go but when i put the standard one on it was fine, will this be because i didnt rejet the carb? and what else should i do it to it to get it to work?

check main jet, it could have the ristricted jet in (52) i think. take it out and put the standard size main jet in (72) also have you taken the restrictor plate off the inside of the variator, next to the rollers.
