re: Motorized Bicycle Take a Tip...Leave a Tip
This isnt the greatest tip, but if your cap is messed up and you need something to try to keep dirt out then the above works. I had tried string wrapped around the cap area which worked, but I wanted something that could slip on and off, so silicone. You only need a trace of grease anywhere you dont want silicone. Too much and you'll have uncured silicone to clean up.
Here's my cap in the attachment.
