    1980 CM400E Left Side Cover Repair

    When I first got the bike I noticed the Left side cover flopping around a little bit. Pulled it off and noticed the front tab was broken and "repaired" with Silicone Bathroom Caulk. Luckily it was a clean brake. Silicone came off easily.

    Was at Ace Hardware and found a small piece of conduit cover for inside a house.

    Trimmed it to fit and scuffed every thing with 60 grit then cleaned with Wax and Grease Remover.

    Epoxied the bottom 1/2. Let it dry for a few days. Then did the top. Got lucky. Both halves fit together perfectly. 2 tiny screws....one in bottom 1/2, one in the top. Stuff is as hard as a rock. Thanks to longdistancerider for pointing me too JB Weld......for Steel, not plastic.

    Can't see the inside from here... or anywhere, unless you remove the cover! Good job saving something very hard to find apparently

    I see them selling for $75.00 to well over $100.00. That's not bad if they're new. A lot I see are junk !

    I'm curious, I see a lot of left side covers for old hondas, but never right side covers, why are the right side covers so rare?

    My Nighthawk has its right side cover still, but all the tabs broke off so the PO drilled a hole through it to run a bolt through. I think I might try repairing it this winter, I could 3D print new tabs and epoxy them on, and then fill the hole and re-paint it.

    Right covers are rare because that cover gets pulled more often to charge/replace/service the battery. The real problem with the tabs is that no one ever cleans and lube the rubbers, so they get cruddy and the tabs bind/stick/glue to them. Then when the owners finds it's stuck uses the "bigger hammer" theory and brute force to remove instead of lighter pressure prying to remove. The CB450SC right cover is getting to unicorn status.

    Well......I guess I'll keep a small amount of grease or oil on the rubbers!

    So what your saying is Im lucky to have a mostly intact right cover? Maybe I should make a mold of it and sell aftermarket right side covers.
