Just about done with my restoration on the '87 K75c, now i'm on to the part I've dreaded the most: replacing the gauge cluster. Part of what retired the bike in the first place was because the glass and tach/speedo got completely smashed while it was in storage. Looking at OEM clusters fills my wallet with fear, so I'm considering aftermarket gauges and the Marulabs Magic Box seems to take out all the guess work with trying to configure a new one. I'm not the picky type, so I figure the box and a cheap speedo would get the job done for less than the cost of an entire "bratbox". Opinions from anyone who's gotten one? or are there cheaper options that plug-in readily/have cheap adapters available?
