3-prong spark plug requirements?

[Deleted member 27734]

So I have the Flying Horse from Bikeberry, and I've got a performance head and 3-pronged spark plug coming in the mail. There were many reviews on Bikeberry, mostly positive but some conflicting. Some people said that the 3-prong will break a 66cc motor while others said it worked perfectly for them. What are your guys' thoughts? Also, it said it should work with stock setup, but I'm wondering if there would be any issues with the CDI or the timing of the motor.


EDIT: sorry if I'm horrible at talking about this, I'm still very new to it all.

ran a lot of those and saw no real diff on many different kit motors - no reason not to use it

My engine came with the 3 prong plug, and it seemed to work fine, but out of curiosity I tried an NGK Iridium, and I like it better. My bike starts easier, and seems to pull better with it.
