Mine is a veritable bin full of parts and I have it now nakedized with the N's lower and upper triple.
In my veritable mystery bin of parts I have a 650 clutch lever and perch, likely a cable and the mechanism and the cover that goes by your foot. Only problem is, I cant find a perch with a mirror mount, else I'd use it. I can get a GS500 brake side block for the clutch and brake side on the sv and fit mirrors to that is what I'm thinking.
Or I have a BMW F 650 lever and perch I could swap instead, that has the mirror mount on it already.
Let me check that and what would turn up would be what's done, I am still working on fitting the rear end of it - just got the fender eliminator and am button up the under side etc a bit cleaner today, likely early in the week I'll make a junkyard run or 2 to find em parts.
Also is the first gen 650 radiator etc the same ? I am just trying to see what else I can use instead so I am not limited by the small numbers of a sv1000 out in the wild.
