Love to see where this goes as my plastic dash secured with jb weld and zip ties (not so good) is falling apart just from me moving about the kart and working on different areas, so I think I"ll eventually follow in ur footsteps with this!
zman, trailtech vapor is a speedometer/odometer/meter of other things. Trailtech makes a buncha stuff like that. I don't know the exact details, but I know it's high-quality!
