I rode down to the local late night auto parts store on my bike running the original Chinese plug which seemed to work fine.
I was looking for the DR8EA plug but all they had was the D8EA. Put that in and it seems to run just great. I am going on a long ride this weekend, I will know more after that.

They do a good job of explaining resistor vs non resistor plugs and other esoterica.
