The Lekkie motor covers are a great item to have on a motor. They provide better motor protection and they have a grease port that lets you add a squirt of grease into the gear area ever so often.
I plan to add a bit a grease every 500 miles or so. Without a port, the cranks, chainring and motor cover had to be removed to add grease.
