Why Won't a Motorcycle Engine Start When Cold?
1 Answers
Typically, this is caused by insufficient cylinder pressure due to cold weather reducing the performance of the engine oil. Other reasons why a motorcycle won't start include: Fuel system faults: Mainly caused by issues with the fuel switch (not delivering fuel), fuel filter (blockage), carburetor (not delivering fuel or overly rich mixture), or bent fuel lines. Electrical faults: Short circuits in electrical components (e.g., ignition switch, ignition coil, ignition module, or magneto failure) or open circuits caused by loose wiring harness connectors. Air pressure faults: Insufficient cylinder compression, improper air filter element resistance, or engine intake/exhaust faults, among others.
