Marthy's Airbox mod


New Member
just a couple questions. with this airbox mod being done whats the solution to the power commander? do you need to have it or not. i have read in a couple places that the bikes run a little on the lean side anyway and if you do this it makes it run leaner. which will burn the valves. so for those of us without a power commander or the likes is this a safe thing to do with out hurting the engine? also without the power commander after doing this mod hows it effect the performance? better low end? better top end or midrange? i guess whats the advantages of doing it without the power commander?


without the PCV the bike will loose bottom end, but mid/high RPM's are better
