High-quality OEM replacement variator guides for 50 cc 4T Chinese scooters (set of 3). Variator guides are the spacers between your variator pulley and the back plate. Regular service of these guides is often overlooked and may cause excess noise and a loss of performance and acceleration. Variator guides are a fairly inexpensive component and it makes sense to check them when replacing your roller or slider weights. We also recommend checking the wear on your clutch while you’re in there, a faulty clutch can be devastating to your pocket and your other transmission components.
