I am a new banshee owner and was going through some clean up on the carbs and noticed i was running jet size of 310. the bike runs really good. the spark plugs look really good. the seem to be the perfect color. not rich at all not lean at all.
so my question is, is 310 way to big. and if not what kind of mods could of the first owner done to keep the plugs looking good with a 310 jet.
second question should i go down a size or two
here is a pic of my plugs. what do you think. this is after 5 tanks of gas.
here the bike.
