I have a 1980 XS650 Special and the Clymer manual seems to indicate a BP8ES spark plug.
This is a non resistor type but NGK shows a replacement as a BPR8ES.(R is resistor type)
Currently I'm running BP7ES with Mike's XS "high output" coil.
I suspect the 7 is a bit on the hot side.
What is the correct plug?
