Why SHERCO 125 HRD SM-SE Motorcycle engine does not start?
- S
  Sherry EvansAug 2, 2025
  If your SHERCO Motorcycle engine won't start, several factors could be to blame. It could be due to a clogged fuel system (fuel line, pump, or filter), in which case you should clean the system. An excessively dirty air filter could also be the cause; clean the air filter. Another potential reason is that the current isn't reaching the spark plug, or the spark plug is dirty, so you should clean or replace the spark plug. If the problem persists after cleaning or replacing the spark plug, it is recommended to contact a Sherco approved dealer. Lastly, if the engine is flooded or the spark plug electrodes aren't properly gapped, open the throttle handle and try starting the engine, and remove, dry, and properly gap the spark plug.
