Motorcycle engines require proper breathing systems to manage pressure buildup during operation; when the breather system becomes clogged, oil pressure increases and can cause oil caps to blow off. Running rich conditions (excessive fuel mixture) can be diagnosed by examining spark plugs for black, soot-covered deposits, which indicates too much fuel is entering the combustion chamber. The root cause may be carburetor issues, cam misalignment, or carbon buildup on valve seals and stems.
