Tach/hour meter
Hi Chuck,
There are two wires. The black wire connects to the engine (ground). The red one is wrapped around the plug wire 3 or 4 times. That's it. The meter has a self contained battery that lasts about 8 years. It's sealed with epoxy so it's vibration and weather resistant. It's very easy to over rev this engine because it pulls the stock gearing well past the 7500 rpm red line with no trouble. I might go to a 44 tooth sprocket after the break-in.
Good luck with your new kit..
