If you have a completely stock midnight special.
IE:stock exhaust and jets could you tell what sort of plug readings you are getting.I just installed 125 main jets and the bike feels slugish in throttle response over 4000rpm but finally gets a good plug colour(light tan).Are these bikes jetted lean from the factory?
