Peugeot speedfight 2 and it won't rev?

carb,fueling,and exhaust systems are all ok. the immobiliser from the aec 400 system has been removed and replaced with an aftermarket cdi unit.

the bike is behaving as if the immobiliser isnt programmed to the key. ie starts fine but wont rev past about 2000 rpm. but the immobiliser isnt even wired in. neither is the origional cdi unit.

can some ne please tellme what i've done wrong?
