thats it in my avatar, got 14s and 70 series with buffed white walls. figure if i upgrade the air system to 3/8 or 1/2 inch valves and systems, it'll be about $1,000, the 22s say about $2,000 so it'll be the same as my friend charging me about $3,000 to do a 2 pump CCE Fatboy system. with all the upgraded checkvalves and all that.
