Hello I have been looking through the internet for things I can do to my nc29 and something that keeps popping up is changing the cdi but I have no idea what the difference between any of them are and how to tell which one is in my bike does anyone know how to tell the difference? Has anyone used a different one and did it make much difference? Thankyou

I think they allow over revving, useful for racing but not so useful for everyday use.

Here is one sold by Graeme France.

Ah alright but mine will go up to 16000 anyway does that mean it's not a restricted one? Thankyou
