Chomp.
There is a forum for Honda scooters that I used to be a member of years ago. It had a HUGE wiki. It is all technical in nature.
There are no discussions or questions allowed in the wiki, only factual information as verified by the powers that be there.
Years, models, parts cross references, maintenance and hop up information. Electrical repair and upgrades. Engine rebuilding and hybridizing of different models.
Parts and supplies vendor listings of who sells what.
You get the idea.
Apparently it took years to "complete" and it was still ongoing the last time I was there.
Such an endeavor should not be taken lightly. The gentleman who started it and nurtured it to fruition described it as practically a 2nd full time job.
