jim smith bought the kepp biz, keith got the apartment back and is building motors for hustler. biscut went to cp , leo is bigcats crewchief , i think brett went to cali, not sure about dave and the rest of the crew. bret hartly has the whole scoop. i'm sure he will chime in. they do need to update the web page , showing 02 prices. i don't belive anything had a patent.
