Big Twin Pre-2010 Retro-Fit Kit
If you purchased your RSD Air Cleaner for your Big Twin prior to 2010 and notice any oil dripping from the bottom filter element, this FREE kit cleans up the pesky problem. We have found that some engines make excessive crankcase pressure causing them to spew a bit more oil than others up through the breathers. This retrofit consists of slotted-head breather bolts and injection molded rubber tubes that fit securely into the backing plate of your existing air cleaner. These parts help route any oil coming out of your breathers right back into your engine without spilling a drop.
