Jetting question for a Full Yoshimura Exhaust
#1
Yoshimura Full Exhaust Picture
This is the exhaust that i want to get on my 04' 400ex. I was just wondering once i got the full exhaust instead of the slip on would i have to jett it and how would i jet it if i did. Also would an air filter help too?
