LooseNUts Posted May 28, 2011 Report Share Posted May 28, 2011 (edited) 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.

ECshee Posted May 28, 2011 Report Share Posted May 28, 2011 5 tanks of gas is too much to tell if your lean or rich. there is a sticky on how to do a plug chop and use that reading to justify your jetting. To know if your jetting is near close, we would also need to know your elevation, mods, and temperature to make a suggestion. Quote Link to comment Share on other sites More sharing options...
LooseNUts Posted May 28, 2011 Author Report Share Posted May 28, 2011 the temp is anywhere from 55 to 80 degrees. elevation is 0 to 500. unsure of mods. i am running T5. and i know the carb has been rejected. Quote Link to comment Share on other sites More sharing options...

Gotta be sure of what your running...and im assuming you mean "rejetted" but if theyre stock carbs, only a filter, and pipes... 300's are probably fine.

LooseNUts Posted May 28, 2011 Author Report Share Posted May 28, 2011 Yes meant "rejetted". Yes it has a K&N and Pipe. So I should go down to a 300? Quote Link to comment Share on other sites More sharing options...
