I found this really good video on YT mostly about greasing and replacing bearings in your 788. He is saying the lack of lube and a good quality lube is a down fall to the 788. Have you guys had problems with your bearings? The way he talks if you grease the bearings before they go bad they will last a very long time. Here is a link to the video, it's in four parts and they are long. (Very long).
