Will the SAMDO LCD Universal Motorcycle Speedometer Gauge work on a TBR7? If so, is there instruction on installation?

It will work fine. Just get one that has similar functions and features to the oem cluster on your bike so you avoid unnecessary warning ⚠️ lights or dummy lights flashing at you. The gauge clusters come with basic instructions. It's up to you to figure out the wiring. You can do this with a wiring diagram, test light, and maybe help from other members who've done it already.
