Hi everyone! I was cleaning my carburetor the other day when I thought of tinkering with my airbox. I know there are a lot of air filters out there, but I'm not sure which are ok. I know that I'll have to adjust the pilot & idle screws, but that'll be just fine. I was thinking about installing a velocity-type or mushroom type air cleaner. Any tips or advice? And do I have to do parallel modifications, like anything concerning the exhaust pipe or such? Any help will be very much appreciated! Thanks!
