Review on Topteng Motorcycle Voltage Regulator Rectifier For Yamaha YFM200 YFM200 Moto-4 200 1985, YFM200 YFM200DX Moto-4 200 1984-1988, YTM200E Tri-Moto 200 1983-1985 by Roberto Manzer

So I recently got my hands on the Topteng Regulator/Rectifier for my Yamaha Moto-4 and while it's not perfect, it gets the job done. The installation process was straightforward and didn't require any fiddling around. However, it's not completely foolproof. I've noticed occasional fluctuations in voltage that make me question its reliability. Overall, it's a decent product that does what it's supposed to, but don't expect perfection.
