I know "Motoporn" Greg and Bob S (he bought my 83 VF750F). I like the REX stock, although I have re-sprung and re-valved the front and went to a more aggressive brake pad. Ben thinking of re-jetting and putting on a pipe, but love the stealth OEM exhaust. Have been putting all of my mod-money into the ZX7, as the 7 is my play bike.
