HI all, put my old cbr600 away for the winter and thinking for taking my Keihin FRC 41mm Flat slide Carburetors off a R1 eng I've got and putting them on the 600.

Any thoughts on issues on this may need different jet..

hi,youd prob be better off sticking a dynojet kit in the original carbs theyre prob 36mm
id have thought 41mm flatslides will kill the low to midrange and still be too big for topend
ready to be corrected though
