Can someone let me know what is the correct spark plug for a 18 Special 125cc engine?

Mine came with a Champion N9YC in it but I think it should be a N21, or maybe something else?

Thanks

MVC,

Usually it would be either a UJ12 or an N21 depending on the thread length in the head. cheers2

Thanks Bruce, I had it in the back of my memory (from about 25 years ago) that it should be a N21. I will check thread length.

preferably an N21 2 piece plug .This was the earlier plug. Could be taken apart and decarbonised etc and re- assebled and re-used virtualy forever.
Klg had asimilar plug from memory called FE20. We used to buy alot more KLG as the cam in atin box with hinged lid which were very handy for keeping smaller parts in. Is the N21 plug still in shops for sale??????????????
