On the site, their was light green,(similar to my k clock set now),and what looked like black, might be dark green? I ordered the dark ones for a F clock set, hoping they will fit? They have a higher red section(does not mater,with the 836 kit I rarely pass 9K, it is still pulling strong though), just wondering bout the Speedo, and rpm ,calibration being the same, start and stop points. My junk set I tore apart for experience and parts are light green k style.
Anyone other than joker make a reasonably priced clamp ring set?
