just wondering if any one can tell me where i can get some adjustable levers eg. Pazzo, Titax. for my 1992 vfr 400 or if its true that if i buy ones for a cbr 600 f4i that they will fit.

I believe that to be correct, or the CBR900 ones and others, there is a thread somewhere about here so have a look with the search function

cbr900 F-18/H-626
thats the actual pazzo part number, but what ever you go for, choose CBR 900RR (93-99) as the fit, thats what i used on mine and they are definetly the same
