I am starting to research an upcoming fun winter project. I am looking to build up my spare kart as a retro racer/practice day toy with a 100cc air cooled formula a style engine. I love the way the old school stuff sound at 20k rpm!
I am going to start searching for used engine on ebay and not looking to spend a ton of money on anything unique or rare. I am ok with doing the full overhaul myself but I need to find an engine that still has decent part/spare support. The stuff all pretty dated now so not sure how realistic that is. I will out source splitting crank to local moto shop but I am capable of doing everything else in house.
I am looking for some recommendations on what to search for on ebay. More about style of engine than overall power so I am ok with something that may not be end all fire breathing beast of engine just a cool toy I can spin to zillion rpm and if I blow it up no big deal just rebuild it again next winter.
So let me know.
