Hey guys, have got my Honda dio running with an 85cc big bore kit, took it for a few laps around the carpark and checked the plug afterwards. It's a light tan colour, as you'd tune it to for performance. BUT, is that too lean for running it in? Shall I richen it? Also, is there a polarity to auto-bystarters? On my new carb the wire colours were reversed on the plug (Green goes to yellow, and vice versa). Does this matter? Thanks, Grant
