Oil sump with site glass for the the Vespa GTS HPE models.

If you ride at high speeds for extending periods of time you may have noticed your HPE engine burning a bit of oil, with this you can easily check the level before you take off in the morning.  Comes with a new gasket.  Piaggio part number 1A012834

When the engine is dead cold and on level ground the sight glass should be about half full.
