  Savannah MartinJul 30, 2025
  High oil consumption in your Husqvarna Motorcycle can be caused by several factors. It could be due to a bent engine vent hose, which requires straightening or replacement. An excessively high engine oil level can also lead to increased consumption, so ensure it's at the correct level. Using engine oil that is too thin (low viscosity) can also be a cause, in which case you should change the engine oil and oil filter and clean the oil screens. Lastly, worn piston or cylinder can be the reason, so you should measure the piston/cylinder mounting clearance.
