How to remove rev limiter on kymco super 9 2007?

The stock cdi box has no rev limiter installed. You might have to get an aftermarket cdi, but if there is no limiter on the stock one then I don't know what good a aftermarket cdi would do for you. There is another derestriction you can do, the carburetors main jet should be replaced with a number 82-85 main jet.
