Ive had my biggun full exhaust system but my mom has never let keep it on because it was too loud, but now she said I can put it on. My question is do I have the change the needle position?Does a 158 mainjet and a 40 pilot jet sound godd? Also will my jetting have to be different if I put in a quiet core? Thanks

with the air box lid on i ususally run around a 152 in the summer and a 155 in the winter. your elevation and temperature you ride in matters too though. i would leave the needle clip position in the stock position for the warmer months and possibly drop the clip down to the 4th position in the colder months.
