Hi, Just started a project on a Teo's 125 and have a work shop manual but there is now information on how the main switch cap comwes away. Don't want to beak, could it be a bayanut or just a lift off? not sure. Anyone help.  

Hi Gordon,

Had a look on google for you, came up with an exploded diagram of the ignition switch, and i assume you're referring to the switch cap cover as shown in the diagram labelled no 6. https://goparts.eu/en/genuine-oem/yamaha/scooter/xn-teo-s-125/2000/battery

On bigger motorbikes generally these are a push on fit with lugs on the main switch body which holds it in place, it takes a small screwdriver to prise the cover over the lugs to remove it.

Not saying yours will be the same but like I said "generally" they are fitted this way so no reason to think it would be alot different.

A close up of the part number seems to confirm this
