Easyboost Starter Motor Cover for Yamaha zuma Installing an overrange / oversize variator (by Malossi, Stage6 etc.) means getting rid of your original starter motor. Easyboost produces these top quality plates to cover the resulting empty space so your variator-side crankcase is sealed once again.
The cover is laser-cut from electroplated steel (high corrosion resistance). A seal and screws are included.
