Whata Difference 40 times over

Looking for a new challenge over this past winter, I decided to see if I could restore a vintage motorcycle purchased over Facebook; a 1972 Honda SL100, “Non-Runner” as described by the seller. Armed with a standard set of sockets, screwdrivers, an endless stream of Youtube instructions and cans of WD-40, I was able to repair and resurrect this gem for a second life. The bike’s age and neglect resulted in almost all of the fasteners to be rust welded in place. After an overnight soak, the sockets and impact driver made quick work to successfully remove all chassis bolts and engine casing screws. With the bike disassembled, the major components were initially cleaned and lubricated with WD40 to assess their mechanical movement and chances for repair. Apart from replacing some of the gummy and corroded carburetor components, the balance of the bike remained original. The rusty spokes and chrome rims were polished with WD40 to recapture their close to original state. This process also acted as a preservative to limit future oxidation. Polishing the aluminum engine showed the greatest contrast in before and after state. The engine was very dull but after 3 rounds of WD40 polishing, the engine’s luster came through. Even the plastic and rubber components showed new life after a squirt and rub with WD40. During the reassembly process, each fastener was lubricated with WD40 to allow for easy fitting and proper torquing to required levels. In the end, a spare fouled spark plug was finally cleaned with WD40 and a small wire brush to a functional sparking unit. Once installed, the bike came to life! The restoration process started in December with the purchase of the bike. WD40 was used continuously in the breakdown, repair, and buildup. Restoration concluded in April with it firing up. These 5 month’s yielded a 50 year old collector item to be admired by others and passed down to the next generation. When in doubt, go with WD40 to get a job well done.

Step 1

The first picture is the Honda SL100 as purchased online. All of the chrome and aluminum components were polished with WD-40. All fasteners were lubricated with WD-40 for easier removal and reassembly. The vintage bike was completed after 5 months of restoration.

Step 2

Step 3

On occasion, a fouled spark plug will develop due to numerous short rides. The carbon build up on the tip of the plug prevents a solid spark. These pictures show the before and after of fouled spark plug subsequent to cleaning with WD-40.

Step 4

Each of the spokes and chrome rims were polished with WD-40 to convert the rust and the dull appearance to a shiney a luster.
