One day when walking by an experimental airplane he was building at his business Air-Ryder, a thought struck Clarke. If the oil cooler he designed for this turbo charged intercooled airplane could cool oil temps from 260 degrees to under 200, certainly he could design something for his Softail.

And he did.

Inspired by aircraft technology, the Oil Bud(tm) is built from aircraft quality materials, polished stainless steel tubing, braided stainless hoses and 6061-T6 aluminum extrusion and welded in header tank assembly.  The temperature regulator starts to open when oil temps hit 185 degrees and fully opens at 205 degrees.  Temperature defferentials from the cold to the hot side of the cooler have been measured up to 35 degrees.

The durable Oil Bud(tm) fits between the frame rails, and once mounted under the motorcycle, it is virtually undetectable. It is designed for 2000-2008 model years Softail. It is easily installed with no major retorfits required.
