Cracked or damaged the left-side engine cover on your 49cc/50cc scooter? This is a brand new replacement crankcase cover from FixRightPro (part COVR-0001). It's designed for the super common GY6 and QMB139 engine families used in tons of Chinese-made scooters and mopeds. This is the \long case\ style cover. If you've got an oil leak from the left side or your cover is physically broken, this part will get you sealed up and running again. It's a critical component that holds in oil and protects the internal parts. Always compare the shape and bolt pattern to your old cover to ensure it's an exact match before ordering. A straightforward repair for scooter owners and mechanics. Get your two-wheeled ride back on the road without leaking oil everywhere.
