Not everything I do is computer related.   I love motorcycles, bought my first one when was 16 and have owned at least one since then.   A while back I finally found a 1983 Kawasaki GPZ 550, the bike I wanted in High School but could not afford.   Funny thing, it cost more to buy the bike as a classic then it did when it was new in 1983.    I rode it for a while and then let it sit, the worse thing that you can do with a carbureted vehicle.  Ethanol gas left to sit goes bad (really bad smell too), and can completed destroy the full system of a motorcycle. First thing was to pull the fuel tank and clean it out.  Found a great three step process for cleaning and resealing the tank.  The fuel petcock was destroyed as well, ordered a new OEM one (not cheap).  Then tackled the carburators (inline 4), complete cleaning and rebuild.    Reassembled the bike and took it for a test drive.   Didn't have the zip that it should, so back to the carburetors.  Took them all apart and purchased the dynojets kit with jets and needles, reassembled with the better parts and now she runs much better. While she is almost done, no old vehicle is ever really done, so I will be tinkering with her for a long time.
