RE: 400 recipe



Don,

Thank you for repeating the recipe. I am thinking of going this way with 
my daily driver. Is there anything that would require detuning for daily 
street use (all weather)?

Also, I am unfamiliar with blocking the heat riser passage with "Propane 
tray is best way". What is a propane tray?

Happy New Year to you and your family, Don.
