hello again with more question im hoping lol. im just trying to get all i can out of my bike and was looking into the cdi i found a few performance cdi's that claim they will remove the rev limiter and adjust the timing curve i think. is this all bs or do these actually work and are they even worth the $15-20 they cost? and if so im assuming i just would need to get an ac 6 pin for a zongshen 250 on a gy-2 thanks so much in advance.
also minor question also saw "performance coils" these i assumed are bs but i may be wrong(
