Nice and easy project! When you replace the slip ring and resolder the terminals to the ends of the coil, make sure you use a small amount of soldering iron but try to build it up to last. The pulley is about 3-times smaller in diameter relative to the one on the crankshaft, meaning it can spin well over 10.000 rpm, on average! I had to redo the soldering on mine when it snapped after a few thousand miles during acceleration
