Modern Vespa

Hi All
My left mirror rotates with breeze, I've tried to adjust it with bolt under handle bar but unable to get to it as I have Oxford heated grip cable running through same hole.

Is there a way to adjust this and if so how would I take off the plastics.

I saw two screws behind bars which release silver control panels.

The centre screen in hub is there anything else? Or am I taking off too many bits to adjust mirror?

Your help be much appreciated. If any pictures or guides?

Mine is 2019 model

Have you tried a different nut? Maybe a nyloc locking nut + split washer?

If it is the stem then try one of these in link below, if it is the actual mirror just grab it with your hand and keep turning backwards until it tightens up.

This same thing happened on my 2016 Mp3.

You might be missing the locking washer that fits with an M8 nut to the base of the mirror stem. From there you'll need a 13mm long neck socket so has enough depth to clear the stem and tighten the bolt. Without that locking washer and enough pounds of force on tightening then the mirror will loosen and swing around when your out riding.
