Onsa-approved challenge!

Easy
>I like riding motorcycles.
>My motorcycle is 25 years old.
>For my summer vacation, I planned on riding to Italy.

Medium
>Before setting off, I decided to do some basic maintenance.
>These tasks only require basic tools, which are included with the motorcycle.
>I am an idiot, however, and fucked this incredibly easy task up.
>As a result, I decided not to take my chances with a dodgy bike and stayed at home watching anime for two weeks instead.

Difficult
>The flow of fuel in an old machine like mine is regulated by a carburettor, which draws fuel into the cylinder by passing the flow of air -- whose speed is regulated by a butterfly valve -- across a narrow opening called a "jet".
>Motorcycle engines need to be light and small, so they are typically made of lighter materials than steel and derive most of their power from combusting smaller amounts of fuel more frequently, that is, at higher RPM.
>Did you know that one of the main challenges of designing an engine, besides striking a balance between performance, durability and cost, is cramming all of the engine parts and the cooling system into a small-enough package that it can fit into the cramped frame of a motorcycle?
