Top quality, made by SIP in the SeriePro range for Vespa. 
 
It is recommended you take out the autolube oil metering feed and add oil manually if you fit a big top end kit, especially if you fit a bigger carb/reed kit. These oil pump hole blanking bungs are ideal to seal the hole for the shaft as not doing this is causing an air leak. 
 
In order to achieve a perfect sealing effect, we reccomend filling the milled notch with Loctite before mounting. 
 
Easy mounted using a light hammer, simply drive covering cap into the engine casing with the sharp side of the cap downwards.
