I accidentally bought a sparkplug (NGK D9EA) for my 1972 SL100 that is heat range 9 instead of the recommended heat range 8, but not practical to send it back. Since most of my riding is at higher speeds (40-55mph) I was thinking this may not be a problem. From what I read it seems that the higher heat range will take longer to get hot, but will be better at dissipating heat. For the $3, I might as well try it? Any cautionary concerns?
Thanks.
