View Full Version : airbox lid
I know it's probably been posted a lot but i can't find the info I'm looking for. If I take off my air box lid will I need to rejet? If so how, can I do it without buying a new parts, and how much will I gain (power and speedwise) Thanks

Yes you have to rejet it cause you are aloowing more air in. You are going to have to buy new jets.
