Hi everyone.

I just brought tzr 50 2007.

Its from spain.

I think it has restrictor ( i think its CDI ) becouse i can't overpass 8000 Rpm. Where can i find that restrictor ( i know its electronical but where should i disconnect somthing ? )

And i think i should be in exhust (?) pipe ?

Max max speed 46~Mp/h

Please help me...

hi mate. the restrictors would most likely be in the form of a resonator pipe on the exhuast( a random pipe coming of the exhuast leading to nowhere) cut this off and weld it over so the pipe is flush where the restricor was. also on geared 50s on the manfold where the carb attaches to the crankcase there is a metal washer which basically pulls the carb out further thus slowing flow down. check the cdi aswell, if theres a random pink wire coming out of it its mostlikely the rev limiter.
