Carburettor before winter storage: drain the float bowl

Fuel left in the float bowl evaporates over a few months of storage and leaves a sticky residue that clogs the jets. In spring such a bike often won't start without cleaning.

• Warm the engine up for a few minutes, then shut it off.
• Turn the fuel tap off if your bike has one.
• Place a container under the bowl drain screw and loosen it a few turns.
• Let the fuel drain completely, then tighten the screw firmly without stripping the thread.
• Dispose of the drained fuel safely, away from open flame and drains.
• If the screw is seized or the carburettors need to come off, take it to a workshop.
