Man I am so happy to see this. I got an old honda motorcyle about 15 year ago and this site was instrumental in helping me develop skills to fix it, and ultimately become a fully fledged shade-tree mechanic.
Also I'd like to add https://www.msgroup.org, another ancient website packed with excellent riding safety tips.
These two sites pretty much got me rebuilding, repairs, and riding motorcycles. Still goldmines today.
