yes you can remove the limiter with a derestricted CDI

This is one from the many sellers on the Bay.
If you want full throttle you have got to give it that via the throttle on the right handle bar.
I do advise you to keep a standard CDI as in my personal opinion their is no need to take the engine anyway near the limiter although I run a 140 which has a lot of torque.
If your running a 125 or 110 I can see it being attractive to remove the limiter so you can make use of the full top end power.
