Will do Bikeguy.
Yeah,it came with a Champion.I got the motor by itself,no carb.,muffler,ect.
The threaded portion is the same as a NGKB5SH,which I just switched to,not wanting to be a guinea pig.Anyway the Champion seems applicable although I don't see China Girl 70 listed under motor models ChampionSparkplugs.com - Vehicle Fitting Results
Maybe Dax got a deal on them.Ron
