I bought two (L&R) replacement front lower frame pieces from Pinwall $14.98 each, plus the shipping. I'm gathering up the parts to do this mod now. Down to finding the appropriate lower hoses/fittings and weld in bungs. I talked to the main guy at Streetmaster, last summer, told me that they wouldn't be doing our bikes, just Bonny s and Thruxtons. I do have a tig welder, but a buzzbox or a 110 volt wire drive would suffice. I will be doing a comprehensive flush, before I let it route oil into my motor, just because. This project should be doable for around $175 max for anybody, IMO
